Attach

The term attach is used on Auras (see enchant), Equipment (see equip), and Fortifications (see fortify), which provide effects to certain other cards for an indeterminate amount of time. These types of cards are used by designating something (usually a permanent) for them to be "attached" to.^[5]: 112

Counter

To counter a spell or ability is to remove it from the stack without resolving its effects, putting it directly into its owner's graveyard.^[5]: 112 Some spells and abilities have an additional clause that replaces the graveyard with another game zone. There are instant spells that will explicitly counter other spells, generally known as "counterspells" after the original card with this effect. Some cards specify that they "cannot be countered".

Exile

To exile a card is to put it into the exile zone, usually as part of a card's effect.^[5]: 113 Starting from the Magic 2010 rules changes, cards that "remove [something] from the game" or "set [something] aside" were issued errata to say "exile [something]" instead.^[6]

Fight

When two creatures fight each other, each creature deals damage equal to its power to the other creature.^[5]: 114 Multiple creatures may fight each other at the same time. Fight is a keyword action that has been sporadically printed in some form since the card Gargantuan Gorilla, but it was not keyworded until Innistrad.

Mill

When a player Mills x cards, they put the top x cards of that library into their graveyard.^[5]: 114 Mill is an action that has been around since Antiquities with Millstone but was never given a keyword until M21, though the term "mill" had been used informally for years prior to the official keywording.^[7]

Sacrifice

To sacrifice a permanent is to put it into its owner's graveyard. A player can only sacrifice a permanent they control. Note that this term is separate from other ways permanents can be put into their owners' graveyards, such as destruction (meaning regeneration has no effect on sacrifice) and state-based actions (a creature having 0 toughness, for example).^[5]: 116 Players are not allowed to sacrifice unless prompted to by a game effect.

Scry

Scry x allows the player to take the top x cards from their deck, examine them, and place any number of them on the bottom of their deck and the rest on top in any order desired.^[5]: 116 Scry originally appeared in Fifth Dawn as a keyword ability, primarily on instants and sorceries as "Scry 2", though it was designed to allow other values. Future Sight added values 1 through 4 and redefined scry to be a keyword action, allowing it to be placed in the middle of an ability rather than as a "tack-on" to other abilities. Scry then appeared in Magic 2011, becoming the first mechanic to be revisited in a core set. Scry also returned in Theros block before becoming an evergreen keyword in Magic Origins.

As of Pro Tour 2015 in Vancouver, the Scry mechanic was introduced to the official tournament rules when taking a mulligan. After all mulligans have resolved, any player whose opening hand contains fewer cards than their starting hand size may Scry 1. This is known colloquially as the "Vancouver mulligan" or "Vancouver rule".^[8] However, it has since been changed to a "London mulligan."

Tap/Untap

To "tap" a card, it is rotated by 90 degrees

To tap a permanent is to rotate the card 90 degrees. This indicates it is being used, often as a cost, or to indicate that a creature is attacking (except for creatures with vigilance). Creatures a player controls that have not been under their control since the beginning of their most recent turn are said to have "summoning sickness" and cannot be tapped for their abilities that include the "tap symbol", nor can they attack, but they can be tapped for costs that use the word "tap" (for example, "Tap two untapped creatures you control").

To untap a permanent is to return it to a vertical orientation, allowing it to be tapped again. A tapped permanent must be untapped before it can be tapped again. However, as introduced in the Shadowmoor block, untapping can also be a cost for activated abilities. It has its own special untap symbol (often called "Q"), and is separate from normal untapping. To pay a cost including the untap symbol, the permanent must be already tapped. If that permanent is also a creature, then, as with the tap symbol, that ability can only be used if the creature has been under its controller's control since the beginning of their most recent turn.

Deathtouch

Deathtouch is a static ability that causes a creature to be destroyed as a result of having been dealt damage by a source with deathtouch. In this way, for a creature with deathtouch, any nonzero amount of damage it deals to another creature is considered enough to kill it.^{[5]: 125 [9]} Deathtouch appears mostly on black cards and green cards, and is often thematically associated with poisonous or cursed creatures. Prior to the introduction of the keyword, similar abilities have appeared mostly on green and black cards, but in most cases those abilities were functionally different (typically triggering on combat damage and/or at end of combat). This ability was first printed on a single timeshifted creature from Future Sight, Thornweald Archer. Older cards with similar or identical abilities, such as Cruel Deceiver, were not changed to gain deathtouch.

Defender

Creatures with defender cannot attack.^{[9][5]: 125} This ability was formerly associated with creature type Wall which had implicit "rules baggage" that prevented attacking. This was simplified with the keyword, which was first used in the Kamigawa block.^[11]

Double strike

A creature with double strike deals both first strike and normal combat damage.^[12][9] For instance, a creature such as Boros Swiftblade which has 1 power, 2 toughness, and double strike would defeat a creature with 2 power and 1 toughness in combat and survive, unless the latter creature also has first strike or double strike, as the first strike damage would destroy it before it would be able to deal damage. If the latter creature instead has 2 toughness, both creatures will be destroyed as the opposing creature survived the first strike, after which both creatures would simultaneously deal regular combat damage to each other. As with first strike, this keyword appears mostly on red and white cards. It first appeared in Legions and was first used in a Core Set in Tenth Edition.

Enchant

This ability is written Enchant (quality) and appears on Auras, a subtype of enchantment spells.^[5]: 52 An Aura enters the battlefield attached to a permanent spell with the quality of its Enchant ability, and can only be attached to a permanent with that quality.^[5]: 52 If an Aura is no longer attached to a permanent with the required quality (such as if the object it enchants leaves the battlefield), it is put into its owner's discard pile. Like protection, the quality can be almost anything, but it normally has a permanent type associated with it, such as "Enchant creature".^[5]: 52 This ability was formerly seen in the type line instead of "Enchantment — Aura"; the wording changed in the Ninth Edition core set, which introduced the Aura subtype.

Equip

This ability is written Equip (cost).^[5]: 126 It is found only on Equipment, a subtype of artifact spells that first appeared in Mirrodin. A player may pay the Equip cost as a sorcery (only during their own main phase when the stack is empty) to attach it to a creature they control.^[5]: 126 That creature becomes "equipped" and can then be referenced by the equipment as the "equipped creature".^[5]: 50 The controller may pay the Equip cost again to move it to another creature. When a creature leaves the battlefield or stops being a creature by some effect, any equipment attached to it "falls off", becoming unattached but remaining on the battlefield.^[5]: 163 Equipment does not "fall off" if another player gains control of either the creature or the equipment – the player who controls the equipment may pay the Equip cost to move it to a creature they control.

First strike

Creatures with first strike deal damage before other creatures in combat.^{[5]: 126 [9]} Therefore, if a creature with first strike deals sufficient damage to kill an opposing creature without this ability, it will not suffer any combat damage from that creature in return.^{[5]: 126 [9]} First strike is often found on red and white creatures, especially soldiers and knights who carry pikes or lances.

Flash

Flash is the keyword of an ability introduced in Mirage.^[13] Artifacts, creatures or enchantments with flash may be played any time their controller could play an instant.^[5]: 126 Older cards with that ability have been updated via rules errata to have flash; this allows them to work with cards such as Mystical Teachings.

Flying

Creatures with flying cannot be blocked except by other creatures with flying and/or reach.^{[5]: 127 [9]} Flying is the most common keyword, and appears in all five colors, but chiefly in blue and white. Creatures with flying are often Dragons, Angels, Birds, and other creatures that have wings; flying can also be possessed by some monks and the Djinn.

Haste

Creatures with the haste ability are able to attack and use abilities that involve the tap symbol on the turn a player gains control of them, instead of waiting until their controller's next turn.^{[5]: 127 [9]} (An effect dubbed "summoning sickness" otherwise prevents a creature from attacking or using abilities with the tap symbol unless its controller controlled it since the start of their most recent turn.^[5]: 52) Haste is an example of a retroactive keywording, as cards from almost every earlier set have possessed "may attack the turn [they] come into play" or "unaffected by summoning sickness", which was replaced by the word "haste". It was later changed to include untapping to activate abilities as well. Creatures with haste are most often red.

Hexproof

A player or permanent with hexproof cannot be the target of spells or abilities controlled by an opponent.^{[5]: 127 [9]} This is similar to shroud, but it does not deny the player (or their allies) the ability to target their own hexproof permanents. Cards that previously had or granted this ability were updated via rules errata to have hexproof with the release of the Commander decks. The Dominaria set introduced a variant of this keyword, hexproof from (quality), which (similarly to protection) prevents a permanent or player from being targeted by spells and abilities with listed quality.

Indestructible

A permanent with indestructible cannot be destroyed by effects that say "Destroy" or by lethal damage.^{[5]: 127 [9]} However, they can be countered, exiled, returned to the hand or library, sacrificed, or killed with effects that lower their toughness to zero. Initially appearing as a quality, indestructible was changed to a keyword so that it can be removed from a card to make it susceptible to being destroyed. Indestructible first appeared in Darksteel, chiefly among artifacts made of the titular metal, and has appeared in colored creatures in subsequent sets.

Lifelink

Permanents with lifelink cause their controller to gain life whenever they deal damage equal to the amount of damage dealt.^{[5]: 128 [9]} Lifelink as a keyword was introduced in Future Sight, though the ability had previously existed on numerous cards, with rules errata retroactively changing these to lifelink. Cards with similar abilities were not changed in this way. Lifelink was a triggered ability when it was issued but is now a static ability due to the Magic 2010 rules changes.^[6] (Cards that previously had a lifelink-like ability have been issued further errata to return them to their original functionality. The lone exception to this is the Mirrodin card Loxodon Warhammer, which, since it was reprinted in Tenth Edition with the lifelink keyword, retains that rather than the original functionality on all editions).^[6] Lifelink is found mostly on white cards, and also on black cards.

Menace

A creature with menace can only be blocked by two or more creatures.^{[5]: 153 [9]} Menace was instituted as a keyword in Magic Origins, and was retroactively applied to previous cards with that ability. Menace appears chiefly on black cards and red cards.

Protection

This ability is written as Protection from (quality).^[5]: 129 A creature with protection from a quality cannot be enchanted, equipped, blocked, or targeted by anything with that quality, and all damage that would be dealt by a source of that quality is prevented, barring exceptions which explicitly state otherwise.^[5]: 129 For example, a creature with protection from red cannot be enchanted by red auras, blocked by red creatures, targeted by red spells and abilities, or take damage from red sources. A common mnemonic for which effects are prevented by protection is the acronym DEBT, standing for "Damage, Enchant (or Equip), Block, Target". Note that the protection ability does not prevent effects that do not target.

If a creature gains protection while some of these effects are present, different things may happen. Any aura, equipment or fortifications attached to it that are no longer legally attached to it "fall off", becoming unattached.^[5]: 129 Auras that are not attached to anything are then put into their owners' graveyards, while equipment and fortifications stay on the battlefield.^[5]: 129 Any spells of that quality (or abilities of permanents of that quality) that target it lose that creature as a target (for example, a creature gained protection from red in response to being targeted with Lightning Bolt). If they no longer have any legal targets, the spell "fizzles" and has no effect.^[5]: 93 However, a creature gaining protection in response to being blocked by a creature does not cause it to become unblocked, though it will prevent all damage that blocking creature would do to the creature with protection.

Initially this ability was limited to "Protection from (color)", but was later expanded to allow "Protection from artifacts" in Urza's Legacy, and officially expanded to allow "Protection from (quality)" in Invasion with the printing of Shoreline Raider. In Conflux, a card called Progenitus has "Protection from everything" – it cannot be blocked, cannot be equipped or enchanted, cannot be targeted by spells or abilities, and cannot be dealt damage. Most cards with protection are either white or an enemy color from the color of protection offered (i.e. most cards with protection from blues are red and green).

Prowess

Prowess is a triggered ability. A creature with prowess gains +1/+1 (until end of turn) whenever a noncreature spell is cast by its controller.^[5]: 152 If a creature has multiple instances of prowess, each triggers separately.^[5]: 152 Prowess was introduced in Khans of Tarkir and became an evergreen keyword with Magic Origins. Prowess appears chiefly on blue cards, and also on red and some white cards. After the release of Hour of Devastation, Prowess is no longer considered Evergreen, and has a Storm scale value of 4, with complications in interactions cited as the cause. As of Core Set 2021, prowess has experienced somewhat of a comeback.

Reach

Reach is a countermeasure to block creatures with flying.^{[5]: 130 [9]} Creatures with flying can only be blocked by creatures with flying or reach. The keyword was introduced in Future Sight, and the flying rules themselves were changed to clarify this interaction. Older cards with the ability to "block as though [they] had flying" were issued rules errata to have reach. Reach is found primarily in green creatures, especially Spiders.

Trample

An attacking creature with trample which is blocked may deal any excess damage, above what is needed to kill the blocker, directly to the defending player.^{[5]: 130 [9]} The choice is made by the attacking player, as circumstances can arise in which "overkilling" the blocking creature is a more advantageous move.^[5]: 130 Trample is most often found on green or red creatures.

Vigilance

Vigilance existed as an ability in Limited Edition Alpha, but was retroactively keyworded beginning with the Kamigawa block. Creatures with vigilance do not tap when attacking ^{[5]: 131 [9]} (prior to being keyworded, these creatures' rules text read "Attacking doesn't cause this creature to tap"), meaning they can still be used during the opponent's turn to block.^[9] Creatures with vigilance are primarily white and secondarily green.

Absorb

This ability is written Absorb x, where x is a quantity of damage prevented on a creature with the ability.^[5]: 144 This ability appears on a single timeshifted creature from Future Sight. Older cards with this ability were not changed to grant absorb.

Adapt

This ability is written (cost): Adapt x and is a tweaked version of the monstrosity mechanic.^[5]: 123 If a creature has no +1/+1 counters on it, the player may pay the adapt cost to put N +1/+1 counters on that creature.^[5]: 123 In comparison to monstrosity, if a creature somehow loses its +1/+1 counters, it can adapt again and pick up more. Alternatively, one can place counters in response to the activation to stop the creature from getting N counters. This mechanic first appears in Ravnica Allegiance and is usually associated with the Simic Combine.

Affinity

This ability is written Affinity for (quality).^[5]: 138 A card with affinity costs 1 generic mana less to cast for each permanent with that quality under the caster's control.^[5]: 138 For instance, an artifact creature that costs 4 generic mana and has 'Affinity for artifacts', would be free if the player casting it controls four or more artifacts, whereas a sorcery with a printed cost of 4 generic mana and 1 blue mana, will cost a single blue mana regardless of whether its caster controls four or five (or more) artifacts. Affinity appeared throughout the Mirrodin block, usually for artifacts. A cycle of five cards in Darksteel had affinity for each of the basic land types.

Afterlife

This ability is written Afterlife x. When a creature with afterlife dies, its controller creates x 1/1 black and white spirit tokens with flying.^[5]: 157 This ability first appears in Ravnica Allegiance and is usually associated with the Orzhov Syndicate.

Aftermath

Aftermath is an ability that appears on instant and sorcery split cards (a card with two separate card images printed on its face next to one another). Only one of the pair of images contains the aftermath ability.^[5]: 156 The half of the pair without the aftermath ability can be cast from the player's hand as normal. Once the physical card is in the player's graveyard (discard pile), the half of the pair that has the aftermath ability can be cast from the graveyard for the cost printed on the upper right of that card, after which the physical card is exiled.^[5]: 156 Functionally, this ability is a hybrid of the kicker and flashback abilities. As with kicker, cards with aftermath have a primary effect and a secondary optional effect that can be produced by paying an additional cost. As with flashback, the second effect can be cast from the graveyard at a time of the player's choosing. Aftermath appears in Amonkhet in all five colors, at rarities of uncommon and above.

Amplify

This ability is written Amplify x. As a creature with amplify enters the battlefield, its controller may reveal any number of creature cards in their hand that share a creature type with the creature . That creature enters the battlefield with x +1/+1 counters on it for each card revealed this way.^[5]: 138 Amplify only appears in Legions.

Annihilator

This ability is written Annihilator x.^[5]: 147 Whenever a creature with annihilator attacks, the defending player sacrifices x permanents.^[5]: 147 Annihilator abilities trigger and resolve during the declare attackers step. The defending player chooses and sacrifices the required number of permanents before they declare blockers. This is a triggered ability that appears exclusively on colorless Eldrazi cards from Rise of the Eldrazi.

Ascend

Ascend is an ability that checks if the player controls ten or more permanents.^[5]: 156 On permanent cards, the check is performed constantly; on instants and sorceries, the check is performed as the spell resolves.^[5]: 156 Regardless of source, if the player passes the check, they gain a unique quality called city blessing for the rest of the game, which empowers all cards with ascend in various ways. This mechanic appears in all colors in Rivals of Ixalan set.

Aura swap

This ability is written Aura swap (cost). By paying the aura swap cost, the player may exchange the Aura with this ability with an Aura card in their hand, if they control and own the Aura with aura swap.^[5]: 144 This ability appears on a single timeshifted Aura from Future Sight.

Bands with other

This ability is a limited version of banding, written as Bands with other (quality). A creature with this ability has banding, but can only band with creatures that have the same ability; e.g. are of the creature type or sub-type (quality), are of the color (quality), and so on. Unlike normal banding, in an attacking band only one creature is required to have the bands with other (quality) ability, so long as all other creatures in the band have the specified quality. All other banding rules apply.^[5]: 132

Prior to the rules revisions made with the release of Magic 2010, "bands with other" worked in a significantly different manner. Rather than limiting a creature with this ability to banding with other creatures with the specified quality, the ability instead required all creatures in the band to have the same "bands with other (quality)" ability or regular banding. The limitations (and counter-intuitiveness) of the ability under these rules led to "bands with other" being called "possibly the worst keyworded ability of all time" by Magic rules manager Mark Gottlieb in the article "Absurd or Ridiculous? You Decide".^[14]

"Bands with other" appears on only nine cards: eight in Legends and one in Unhinged. The only objects that natively have the ability are Wolves of the Hunt tokens created by the card Master of the Hunt and the Unhinged card Old Fogey.

Battle cry

When a creature with battle cry attacks, all other attacking creatures get +1/+0 until the end of the turn.^[5]: 148 Battle cry was introduced in Mirrodin Besieged and appears on Mirrodin cards.

Bestow

This ability is written Bestow (cost) and appears on enchantment creatures.^[5]: 151 A creature with bestow gives the player the option to cast it as an Aura that enchants a creature, granting that creature its power, toughness, and abilities. A bestow card cast for its normal cost will enter the stack as a creature spell.^[5]: 151 By choosing to pay the alternative cost, which is a static ability, it becomes an Enchantment-Aura spell; if the creature it targets leaves the battlefield before the bestow card resolves or while the bestow card is enchanting the creature, the bestow card enters the battlefield as an enchantment creature – unlike a regular aura card which would go to the graveyard.^[5]: 151 This mechanic first appeared on some enchantment creatures from the Theros block.

Bolster

This is a keyword action, written Bolster x. When a player bolsters, the player chooses one of their creatures with the lowest toughness among them and puts x +1/+1 counters on it.^{[5] : 121} The bolster effect does not target; the choice of creature is made at the resolution of the spell or ability. It first appeared in Fate Reforged.

Bloodthirst

This ability is written Bloodthirst x. A creature with bloodthirst x enters the battlefield with x +1/+1 counters on it if an opponent had been damaged during that turn.^[5]: 141 Bloodthirst appears in Guildpact and is the ability associated with the Gruul Clans. It is the returning mechanic in Magic 2012, where it can be found mostly on black and red cards.

Bushido

This ability is written Bushido x. When a creature with bushido blocks or becomes blocked, it gets +x/+x until end of turn.^[5]: 139 Bushido appears on all Samurai in the Kamigawa block, and only on Samurai. Earlier cards with this ability were not given errata to have bushido.

Buyback

This ability is written Buyback (cost). It appears on instants and sorceries and is an additional, optional cost when casting the card. If the buyback cost was paid, the card returns to its owner's hand upon resolving, instead of going to the graveyard.^[5]: 134 Buyback first appears in the Tempest block.

Cascade

When a spell with cascade is cast, its controller reveals cards from the top of their deck until a non-land card that has a lower converted mana cost is revealed. That player may then (in addition to the original spell) cast the revealed spell without paying its mana cost; all other revealed cards are put on the bottom of the deck in a random order.^[5]: 147 Cascade was introduced in Alara Reborn and is the main feature of the "Chaos Reigns" deck from the Planechase 2012 expansion.

Champion

This ability is written Champion a (type). It is an evolution-style mechanic that mimics a creature changing into a "new improved version".^[15] When a creature with champion enters the battlefield, its controller must exile a card they control of the appropriate type, or sacrifice the champion. When the creature with champion leaves the battlefield, the creature it "championed" (the exiled card) is returned to the battlefield. Most creatures with champion replace a creature that shares their own creature type, but those with the changeling ability have the generic "Champion a creature".^{[5] : 145} Champion was introduced in Lorwyn.^[15]

Changeling

Changeling is a keyword that gives a card all possible creature types, similar to the ability of Mistform Ultimus.^{[5]: 145 [15]} It appears on certain shapeshifter creatures and tribal spells in Lorwyn.^[15]

Cipher

Cipher is printed on sorceries and represents two effects. When a spell with cipher resolves, its controller may exile the spell "encoded" on a creature they control. Then, whenever that creature deals combat damage to an opponent, its controller can cast a free copy of the encoded spell.^[5]: 150 Cipher appears in Gatecrash as the guild keyword of House Dimir.

Clash

Clash is a keyword action that determines the results of a spell or ability. When a card says to clash, its controller chooses an opponent to clash with, and each player involved in the clash reveals the top card of their deck, then puts it on the top or bottom of that deck. The winner of the clash is the player who revealed the card with the highest converted mana cost. If there is a tie, there is no winner.^[5]: 119 All cards with clash grant a bonus effect if their controller wins the clash. Clash was introduced in Lorwyn.^[15]

Conspire

As a player casts a spell with conspire, they may pay the optional, additional cost of tapping two creatures that share a color with the spell. They then copy the spell and may choose new targets for the copy.^[5]: 146 Conspire appears on instants and sorceries in Shadowmoor.

Convoke

As a spell with convoke is cast, its controller may tap any number of creatures. Each creature tapped reduces the card's mana cost by 1 generic mana or 1 mana of the tapped creature's color.^[5]: 141 For example, a player may pay for Conclave's Blessing, which costs 3 generic and 1 white mana, by tapping four creatures, at least one of which must be white. Convoke appears in Ravnica: City of Guilds and Guilds of Ravnica and is the ability associated with the Selesnya Conclave. Convoke is also the returning keyword mechanic for the Magic 2015 core set, where it appears in all colors.

Crew

This ability is written as Crew x. It appears only on vehicles, a new subtype of artifacts introduced during the Kaladesh block. Vehicles are not creatures by default, but have a power and toughness printed in a different colour. A vehicle's controller can pay the crew cost by tapping any number of creatures with total power greater than or equal to x, which turns the vehicle into an artifact creature until end of turn.^[5]: 155

Cumulative upkeep

This ability is written Cumulative upkeep (cost). At the beginning of each of its controller's upkeeps, an "age counter" is put on the card. The player must then either pay the cumulative upkeep cost for each age counter on the permanent, or sacrifice it.^[5]: 133 The ability was originally designed to represent an ever-climbing cost, eventually forcing the player to sacrifice the card and lose its benefits, although later incarnations provide a benefit for the number of age counters on the card. The ability first appeared on the card Cyclone from Arabian Nights, and was first keyworded in Ice Age. The mechanic also appeared in Mirage block, with Weatherlight offering a number of twists on the upkeep cost, and in Coldsnap.

Cycling

This ability is written Cycling (cost). A player with a card with cycling in hand may pay the cycling cost, discard the card, and draw a new card. Cycling cards appeared in the Urza block, the Onslaught block,^[16] the Alara block, and the Amonkhet block. A variant of this keyword is typecycling. Future Sight introduced the first cards with unusual Cycling cost, like discarding a card or paying life.

Dash

This ability is written Dash (cost) on creature spells. A player casting a card with Dash may opt to pay its Dash cost instead of the normal cost. If the Dash cost is chosen, the creature gains Haste until the end of turn, and is returned to its owner's hand at the end of turn.^[5]: 152 The mechanic first appeared in Fate Reforged.

Daybound & Nightbound

This mechanic was introduced in the Innistrad Midnight Hunt set. Cards featuring daybound and nightbound will transform when certain rules are met.^[17] If it is day, to transform to night the active player must not cast any spells during their turn. To transform back to day, the active player must cast two or more spells during their last turn. Cards featuring this new mechanic can be flipped to either side depending if it is day or night.^[17]

Delve

When playing a card with delve, its controller may exile any number of cards in their graveyard. For each card exiled, the spell costs 1 colorless mana less to play.^[5]: 144 This ability first appeared on timeshifted cards from Future Sight, and returned in the set Khans of Tarkir .

Detain

Detain is a keyword action introduced in Return to Ravnica that appears on blue and white cards of the Azorius guild. When a player detains a permanent, the detained permanent cannot attack, block, or activate abilities until the start of the player's next turn.^[18]

Devour

This ability is written Devour x. As a creature with devour enters the battlefield, its controller may sacrifice any number of creatures in order to put x +1/+1 counters on the devouring creature for each creature sacrificed.^[5]: 147 Devour appears on Jund cards in the Alara block.

Dredge

This ability is written Dredge x. If a card with dredge is in the player's graveyard, that player may put the top x cards of their deck into their graveyard and return the card with dredge to their hand, instead of drawing a card from their deck. A player cannot do this if there are fewer than x cards in their library.^[5]: 141 Dredge appears in Ravnica: City of Guilds and is the ability associated with the Golgari Swarm.

Echo

This ability is written Echo (cost). Cards with echo require their echo cost to be paid at the beginning of their controller's upkeep, the turn after the card was played or gained control of. If the echo cost is not paid, then the card is sacrificed.^[5]: 135

In the Urza block, this ability was written only as "Echo" with the echo cost always equal to the card's mana cost.^[5]: 135 The rules were altered for echo's return in Time Spiral to be written as echo (cost) instead, and all previous echo cards were issued rules errata to have their echo cost equal to their mana cost.^[5]: 135 Additionally, although all echo cards in Time Spiral had echo costs equal to their mana costs, Planar Chaos introduced permanents with echo costs different from their mana costs, and Future Sight introduced echo costs that are not simply mana payments.

Embalm

This ability is written Embalm (cost) and appears on creature cards. When a card with this ability is in a player's graveyard, that player may pay its embalm cost to exile the card and put a token into play that is a zombie copy of the creature, in addition to the creature's other creature types (e.g., a Zombie Angel instead of an Angel).^[5]: 156 This allows a player to gain a second use from a card with benefits from other cards that interact with zombie creatures. Embalm is an activated ability (the token is created, not cast) and may be played only when the player could cast a sorcery.^[5]: 156 This keyword is similar to flashback, but is found on creature cards rather than instant and sorcery cards. Embalm appears in Amonkhet, primarily appears on blue and white cards. Each card with embalm has its own printed token card, with an alternate artwork showing a mummified version of the original creature.

Emerge

Emerge is an ability allowing the player to pay an alternate mana cost by sacrificing a creature and paying the difference between the Emerge cost and the sacrificed creature's converted mana cost.^[5]: 154 It appears in Shadows over Innistrad on Eldrazi creatures.

Entwine

This ability is written Entwine (cost). All cards with entwine are modal spells with two choices. Normally, a player chooses one mode or the other. If the card's entwine cost is paid in addition to its regular cost, both effects happen.^[5]: 138 Entwine appears in the Mirrodin block.

Epic

Epic has two effects: first, after a player casts a spell with epic, they can no longer cast spells for the remainder of the game. However, at the beginning of each of they upkeeps for the rest of the game, the player puts a new copy of the epic spell on the stack. This does not count as "casting" it (so it does not become a useless ability) and no mana payment is required.^{[5]: 140, 141} Epic appears only on a cycle of five rare sorceries in Saviors of Kamigawa.

Evolve

Evolve is a keyword on creatures which allows them to grow larger. Whenever a creature enters the battlefield under the player's control, if that creature has larger power or toughness than the creature with evolve, that player puts a +1/+1 counter on the creature with evolve.^[5]: 150 Evolve was designed by a contestant during The Great Designer Search II and appears in Gatecrash as the guild keyword of the Simic Combine.

Evoke

This ability is written as Evoke (cost) and is an alternate cost for a creature, generally far lower, with the condition that the creature must be sacrificed upon entering the battlefield. All cards with evoke have additional effects upon entering or leaving the battlefield. The creature's controller may choose whether the sacrifice occurs before or after the additional effect(s).^[19] Evoke appears in Lorwyn^[19] and Morningtide.

Exalted

Exalted originally appeared on cards within the Bant colors in the Alara block. When it reoccurred in Magic 2013, 5 black cards were given the mechanic. When any creature a player controls attacks alone, it receives +1/+1 until end of turn for each permanent with the exalted keyword that player controls.^[5]: 147

Exert

Exert is an ability that appears on creature cards. Depending on the card, a creature with this ability can be exerted to activate its ability, or can be exerted during attack for an additional bonus, at a cost of that creature not untapping during its controller's next untap step. Exert appears in both sets of the Amonkhet block, exclusively on green, red, and white cards.

Exploit

Exploit is an ability that appears on creatures. It gives the player who casts it the option to sacrifice a creature they control when it enters the battlefield, so that a specified ability will trigger.^[5]: 153 Exploit appears in Dragons of Tarkir and in Innistrad Crimson Vow

Explore

Explore is a keyword action associated with creatures. When a creature explores, its controller reveals the top card of their library. If it is a land card, they put it in their hand; otherwise, they put a +1/+1 counter on that creature and can choose to leave that card on top or send it to their graveyard.^[5]: 123 Explore appears in both sets of Ixalan block in all five colors.

Extort

Extort is a keyword which allows a player to slowly drain life from opponent(s). When casting a spell, the player may pay one white or black mana. If they do, then each opponent loses one life and the player gains one life for each point of life their opponent(s) lost.^[5]: 150 Extort appeared in Gatecrash as the guild keyword for the Orzhov Syndicate.

Fabricate

This creature ability is written as Fabricate x. When a creature with fabricate enters the battlefield, its controller either puts x +1/+1 counters on it or creates x 1/1 colorless Servo artifact creature tokens.^[5]: 155 Fabricate appears in Kaladesh

Fading

This ability is written as Fading x. A permanent with fading enters the battlefield with x fade counters on it. At the beginning of its controller's upkeep, a fade counter is removed; if a counter cannot be removed, the card is sacrificed. Fading is exclusive to Nemesis. It is extremely similar to the Planar Chaos keyword vanishing.^[20]

Fateseal

This keyword action is written Fateseal x. To fateseal, a player looks at the top x cards of an opponent's deck and may put any number of those cards on the bottom of that player's deck.^[5]: 119 Thus, this ability is functionally a scry on the opponent's deck; fateseal was dubbed "evil scry" while in design.^[21] Fateseal exclusively appears on timeshifted cards from Future Sight.

Flanking

When a creature with flanking is blocked by a creature without this ability, the blocking creature gets −1/−1 until end of turn.^[5]: 133 The effect is cumulative; multiple instances of flanking will effect a greater penalty, though a blocking creature only needs one instance to avoid the effect.^[5]: 133 Flanking first appears in the Mirage block.

Flashback

This ability is written Flashback (cost) and appears on instants and sorceries. When a card with this ability is in a player's graveyard, that player may pay its flashback cost and cast the card from the graveyard. The card is then exiled.^[5]: 136 This allows a player to get a second use from a card. Flashback was introduced in the Odyssey block, where cards with an ability that acted from the graveyard have small headstone markers in front of their names. They reappeared in Time Spiral and Innistrad blocks (without the headstone marker).

Flip

Flip is a keyword action that deals with specially printed cards known as "flip cards". Each of these cards has two sets of normal card attributes (e.g. name, rules text, power and toughness): one right-side-up above the card's image and one upside-down (with no mana cost) below the image. Flip cards enter the battlefield unflipped, with only the former set of attributes applying. Once certain conditions are met, the player flips the card (rotating it 180 degrees) and the second set of attributes come into effect. Once flipped, a card cannot be unflipped (except by leaving the battlefield and returning), and effects that would "flip" a card that is already "flipped" do nothing.^[5]: 172 Flip cards appear in the Kamigawa block. Although "flipping" is often colloquially used to refer to morphing and transforming cards, they are distinct mechanics.

Forecast

This ability is written Forecast — Cost: Effect. During a player's upkeep, if they have a card with forecast in their hand, they may pay the forecast cost to activate its forecast ability. The cost always includes revealing the card until the end of the upkeep. A player can only do this once per turn per forecast card.^[5]: 142 Forecast appears in Dissension and is the ability associated with the Azorius Senate.

Foretell

To foretell a card, a player pays two mana (of any combination of colors) and then exiles the card with foretell ability faced down. In any future turns, they can cast the card from exile by paying the foretell costs (this is the mana cost listed on the card) rather than paying the mana cost of the card. They may not cast the card from exile on the same turn that it was exiled.^[16]

Fortify

This ability is written Fortify (cost). It is found only on fortifications, a subtype of artifacts. A player pays the fortify cost as a sorcery (only during their own main phase when the stack is empty) and attaches it to a land they control. That land becomes "fortified" and can then be referenced by the fortification as the "fortified land". Other than attaching to lands instead of creatures, the rules for fortifications are similar to those for equipment.^{[5]: 50, 51, 144} Fortify appears on a single timeshifted artifact from Future Sight, Darksteel Garrison.

Frenzy

This ability is written Frenzy x. When a creature with frenzy attacks and is not blocked, it gets + x /+0 until end of turn.^[5]: 144 This ability appears on a single timeshifted creature from Future Sight, Frenzy Sliver.

Graft

This ability is written Graft x. All creatures with graft are 0/0 creatures that enter the battlefield with x +1/+1 counters on them. Whenever another creature enters the battlefield, a player may move one +1/+1 counter from any number of creatures with graft they control onto that creature.^[5]: 142 Graft appears in Dissension and is the ability associated with the Simic Combine.

Gravestorm

When a player casts a spell with gravestorm, they put a copy of that spell on the stack for each permanent that was previously put into a graveyard that turn.^[5]: 144 This ability is similar to storm and appears on a single timeshifted card from Future Sight, Bitter Ordeal.

Haunt

Haunt appears on creatures, instants, and sorceries. When a creature with haunt dies or when an instant or sorcery with haunt resolves, the ability triggers causing the card to be exiled "haunting" a creature. Haunt allows a player to use an effect twice: once when the spell is played (or the creature enters the battlefield), and once when the creature it haunts is put into a graveyard. Haunt appears in Guildpact and is the ability associated with the Orzhov Syndicate.

Hideaway

When a card with hideaway enters the battlefield, its controller chooses one card from the top four of their library and exiles that card face-down.^[5]: 145 Each card with hideaway also has another ability that allows its controller to play the "hidden" card, without paying its mana cost, under certain conditions. Hideaway appears only on a cycle of lands from Lorwyn, along with a creature from Modern Horizons 1, and most recently on a cycle of enchantments from Streets of New Capenna.

Horsemanship

Horsemanship parallels flying in that creatures with horsemanship can only be blocked by other creatures with horsemanship.^[5]: 135 There is no exception analogous to reach. Horsemanship is mostly unique to the Portal Three Kingdoms set, so very few cards make use of the keyword.

Infect

Creatures with infect deal damage to other creatures in the form of −1/−1 counters, similar to wither, and to players in the form of poison counters.^[5]: 148 A player who receives 10 poison counters loses the game.^[5]: 162 Infect appears on Phyrexian cards in the Scars of Mirrodin block.

Jump-start

Spells with jump-start can be cast from the graveyard with the additional cost of discarding a card. After the spell leaves the stack, it is exiled.^[5]: 157 Jump-start appears in Guilds of Ravnica and is associated with the Izzet League.

Kicker

This ability is written Kicker (cost). The kicker cost is an additional and optional cost that can be paid when the card is cast. If the card is "kicked", an ability of the card takes effect. Some cards have multiple kicker abilities; a player may choose to pay any, all, or none of these.^[5]: 136 Kicker was introduced in the Invasion block and is the returning mechanic in the Zendikar and Dominaria blocks.

Level up

This ability is written Level up (cost). Any time they could cast a sorcery, a player may activate the level up ability of a "leveler" creature to put a level counter on it. Leveler creatures increase in power and gain new abilities as they accumulate level counters, as indicated by the three striped bands in the text box.^{[5]: 147, 172, 173} Level up appears in Rise of the Eldrazi.

Living weapon

When an equipment with living weapon enters the battlefield, its controller puts a 0/0 black Germ creature token onto the battlefield then attaches that equipment to the token.^[5]: 148 All cards with living weapon give the equipped creature a toughness increase to compensate for the Germ's 0 toughness; the player may attach the equipment to a different creature, but the Germ will be instantly sent to the graveyard. Living weapon was introduced in Mirrodin Besieged and appears on Phyrexian cards.

Madness

This ability is written Madness (cost). At the time a player discards a card with madness, they may pay its madness cost and cast the card.^[5]: 136 Madness first appeared in Torment, and the rules for madness were subtly shifted for its reappearance in Time Spiral block, where the vast majority of madness cards were black. A madness cost is usually cheaper than the normal mana cost of a card (but the Future Sight set introduced Ichor Slick whose madness cost is more expensive than its normal cost). The rules for madness were changed again when it was reintroduced for Shadows over Innistrad.

Manifest

This ability is written Manifest [one or more cards], most frequently manifest the top card of your library. When the player manifests a card, the player puts it onto the battlefield face down, disguising its true identity from their opponents. While face down, it's a 2/2 colorless creature with no name, no abilities, and no creature types. Face-down cards act as creatures: they can attack and block, be targeted by spells and abilities affecting creatures, and be modified with auras and equipment.^[5]: 121

However, if the face-down card is a creature card then it can be turned face-up for its full mana cost whether it has this ability on its own or not. If the card has the morph ability, the controller can use this ability to turn the card face-up, regardless of the card's type; megamorph is treated the same way. These uses of morph and megamorph are considered 'special actions' and do not hit the stack.^[5]: 121

As always, any face-down card must be revealed at the end of the game or when it is moved to any zone other than the battlefield, including exile. Also, manifested cards are treated identically to morph cards in that they are distinct from one another and must be distinguishable from other manifested cards throughout the game.^{[5]: 169, 170}

Meld

Meld is a keyword action where two specific cards can be exiled and then returned to the battlefield combined into a single creature.^[5]: 176 This mechanic is featured in the Eldritch Moon set expansion.

Mentor

Whenever a creature with mentor attacks, a +1/+1 counter may be placed on another attacking creature with lesser power. If a creature has multiple instances of mentor, each triggers separately.^[5]: 137 This ability is featured in the Guilds of Ravnica expansion and is associated with the Boros Legion.

Miracle

This ability is written Miracle (cost). If the first card a player draws during any turn has miracle, they may reveal the card. If the card is revealed, the player may then cast the card for its miracle cost.^[5]: 149 Miracle appears in Avacyn Restored. Cards with miracle have a special border that appears as if the art is bathed in light.

Modular

This ability is written Modular x. A creature with modular enters the battlefield with x +1/+1 counters on it, and when that creature is put into a graveyard, its controller may put all the +1/+1 counters on that creature onto a target artifact creature.^[5]: 138 Modular appeared in Darksteel and on one card in Fifth Dawn (Arcbound Wanderer). Modern Horizons 2 added 8 new creatures with Modular and even a land with it.

Monstrosity

This ability is written (Cost): Monstrosity x. If a creature is not monstrous yet, this ability makes that creatures monstrous and it gets x +1/+1 counters.^[5]: 120 Some creatures with this ability gain an additional effect once they become monstrous.

Morph

This ability is written Morph (cost). A card with morph may be cast face-down by paying 3 generic mana. While face-down, the creature is a colorless, nameless and typeless 2/2 creature. At any time, a player may pay the creature's morph cost and turn the card face-up.^[5]: 137 Many cards with morph have additional abilities when they are turned face-up. Morph was introduced in the Onslaught block.

Only cards with morph may be played face-down. If a card without morph is turned face-down by an effect, it cannot be turned face-up (unless the effect specified otherwise), because it has no morph ability with which to do so. At the end of the game, or whenever a face down creature would leave the battlefield, it is revealed to all players. In addition to providing information to players, this ensures that players do not cheat by playing cards without morph face-down.^[5]: 171

Multikicker

Multikicker is a variant of the kicker keyword, written Multikicker (cost), where the cost can be paid any number of times when the card is played, as opposed to the limit of one as defined in the original kicker ability. Cards with multikicker have an ability that references the number of times the card was "kicked".^[5]: 136 Multikicker appears in the Worldwake set.

Mutate

If the player casts a spell for its mutate cost, they put it over or under a non-Human creature they owns. The creature mutates into the creature on top plus all abilities from under it.^[5]: 158

Ninjutsu

This ability is written Ninjutsu (cost). If a player has a Ninja in hand and controls an attacking creature the opponent has declined to block, they may pay its ninjutsu cost, return the unblocked creature to their hand, and put the Ninja onto the battlefield tapped and attacking.^[5]: !40 Ninjutsu appears in Betrayers of Kamigawa and Kamigawa: Neon Dynastyand only on Ninja creatures.

Offering

This ability is written (Creature type) offering. A player may cast a creature with the offering ability as an instant (similar to flash) but must sacrifice a creature of the stated type and pay the difference in mana cost between the sacrificed creature and the creature with offering.^[5]: 140 Offering only appears on a cycle of five legendary Spirits in Betrayers of Kamigawa.

Overload

Overload is a keyword for instants and sorceries used by the Izzet League in Return to Ravnica. By paying the more-expensive overload cost instead of the regular mana cost, the spell can affect all possible targets, rather than a single one.^[18]

Persist

When a creature with persist is put into a graveyard from the battlefield, if it had no −1/−1 counters on it, it is returned to the battlefield under its owner's control with a −1/−1 counter on it.^[5]: 146 Persist appears in Shadowmoor and Eventide.

Poisonous

This creature ability, written Poisonous x, originated in the Legends set. Whenever a creature with poisonous deals combat damage to a player, that player gets x poison counters.^[5]: 145 A player with ten poison counters loses the game.^[5]: 162 Cards with the ability appeared in small quantities up to the release of Fifth Edition, after which the ability was retired until Time Spiral block. Poisonous was keyworded in Future Sight, though older cards with the ability have not been changed to have poisonous due to minor text variations between cards. This ability was supplanted by the infect ability of the Scars of Mirrodin block.

Populate

Populate is a keyword action introduced in Return to Ravnica that appears on green and white cards of the Selesnya Conclave. To populate, a player puts a token onto the battlefield that's a copy of a creature token they control.^[18]

Proliferate

Proliferate is a keyword action introduced in Scars of Mirrodin. To proliferate, a player chooses any number of permanents and/or players with a counter (e.g. a Planeswalker loyalty counter, a +1/+1 counter, a poison counter), then gives each exactly one additional counter of a kind that permanent or player already has.^[5]: 121

Provoke

When a creature with provoke attacks, its controller may target a creature the defending player controls, forcing it to untap (if it is tapped) and block the attacking creature if it is able to do so.^[5]: 138 The ability can choose a creature that is not able to block the creature with provoke. Provoke is cumulative,^[5]: 138 though no creature has more than one instance of it. Provoke only appears in Legions.

Prowl

This ability is written Prowl (cost) and is an alternate cost. A player can cast a card for its prowl cost if the player controls a creature of the same type which dealt damage to a player that turn.^[5]: 145 Most cards with prowl have an additional effect if cast for their prowl cost. Prowl appears in Morningtide exclusively on cards that contain the Rogue subtype.

Rampage

This ability is written Rampage x. When a creature with rampage becomes blocked, the creature gains +x/+x until end of turn for each creature beyond the first assigned to block.^[5]: 132 Mirage was the last set to print new cards with rampage (although Time Spiral reprinted Craw Giant), and 5th Edition was the only Core Set to include cards with rampage.

Rebound

The rebound ability allows a player to cast an instant or sorcery spell more than once. When a spell with rebound is cast from a player's hand, that player exiles it, and during their next upkeep may cast the spell again without paying its mana cost (similar to suspend).^[5]: 148 Rebound was introduced in Rise of the Eldrazi and was brought back in Dragons of Tarkir.

Recover

This ability is written Recover (cost). Whenever a creature is put into a player's graveyard from the battlefield, all cards with recover in that player's graveyard trigger. That player may then pay each card's recover cost; if the cost is paid, the card is put into the player's hand, but if it is not paid, the card is exiled.^[5]: 142 Recover appears in Coldsnap.

Reinforce

This ability is written Reinforce x — (cost). A player may discard a card with reinforce from their hand, pay its reinforce cost, and put x +1/+1 counters on a target creature.^[5]: 146 Reinforce appears in Morningtide.

Retrace

Retrace appears on instants and sorceries. It allows players to replay a spell from the graveyard by paying its mana cost and all associated costs with the additional cost of discarding a land card.^[5]: 146 Unlike with flashback, a card cast from the graveyard with retrace is not exiled, and returns to the graveyard after it resolves. Retrace appears in Eventide.

Riot

As a creature with riot enters the battlefield, its controller can choose it to enter with a +1/+1 counter or haste. If a creature has multiple instances of riot, each triggers separately.^[5]: 147 Riot appears in Ravnica Allegiance and is usually associated with the Gruul clans.

Ripple

This ability is written Ripple x. When a spell with ripple is cast, its controller may reveal the top x cards of their deck. If any of them have the same name as the spell with ripple that was cast, then the player can cast those cards without paying their mana costs (this triggers their ripple abilities, so a player can ripple again). Any cards not thus cast are then put on the bottom of that player's deck.^[5]: 143 Ripple appears in Coldsnap, where all cards with the mechanic have ripple 4.

Scavenge

This ability is written Scavenge (cost). Any time they could cast a sorcery, a player may exile a card with scavenge from their graveyard to put a number of +1/+1 counters onto a target creature equal to the power of the creature with scavenge. Scavenge appears on green and black cards of the Golgari Swarm in Return to Ravnica.^[18]

Shadow

Creatures with shadow can only block or be blocked by other creatures with the shadow ability.^[5]: 135 Shadow was introduced in the Tempest block.

Soulbond

Creatures with soulbond can be paired with other creatures (with or without soulbond) when either creature enters the battlefield.^[5]: 149 When paired, each of the paired creatures receives the ability printed on the soulbond creature's card (if both creatures have soulbond, they each receive both abilities). Creatures remain paired as long as they remain under the control of the caster. Soulbond appears in Avacyn Restored.

Soulshift

This ability is written Soulshift x. When a creature with soulshift is put into a graveyard from the battlefield, its controller may return a spirit card with converted mana cost x or less from their graveyard to their hand.^[5]: 139 Almost all cards with soulshift are spirits with a soulshift number one less than their converted mana cost (to prevent them from returning themselves); a notable exception is Promised Kannushi (which is a human druid, not a spirit). Soulshift appears in the Kamigawa block.

Spectacle

This ability is written Spectacle (cost). A player can cast a spell for its spectacle cost if an opponent lost life during the turn.^[5]: 157 In some cases additional benefits are provided for paying the spectacle cost. This ability is introduced in Ravnica Allegiance and is associated with the Rakdos Cult.

Splice

This ability is written Splice onto (quality) (cost). As a player casts a spell with a given quality, they may reveal any number of cards in their hand with splice onto that quality, and pay their splice costs; each splicing card's effects are added to those of the spell cast, while the cards spliced onto the spell are kept in the player's hand. These effects are placed after the played spell's effects.^{[5]: 139, 140} One card, Evermind, has no mana cost (meaning it cannot be cast normally), but it does have a splice cost. Splice appears in the Kamigawa block, where the quality was limited to Arcane.

Split second

While a spell with split second is on the stack, players cannot cast spells or activate non-mana abilities. Triggered abilities and certain special actions that do not use the stack (such as un-morphing a face-down permanent) can be played as normal.^[5]: 143 Split second is similar to the defunct interrupt card type, except that a card with split second cannot be cast while another card with split second is on the stack, whereas one interrupt card could be played in response to another. Split second appears in the Time Spiral block.

Storm

When a spell with storm is played, the player puts a copy of that spell on the stack for each spell cast before the storm spell that turn, getting that many instances of the spell.^[5]: 138 Storm was introduced in Scourge.

When the last counter is removed, the spell is cast without paying its mana cost and, if it is a creature, it gains haste.^[5]: 143 Cards may be given suspend and have time counters put on them when they are exiled by an effect. In particular, a cycle of cards from the Future Sight set can "re-suspend" themselves after they resolve. Suspend appears in the Time Spiral block.

Any time a sorcery could be cast, a player may pay a creature's transfigure cost and sacrifice it to search their deck for a creature with the same converted mana cost as the sacrificed creature and place it onto the battlefield.^[5]: 145 It is a variant on the transmute ability. This ability appears on a single timeshifted creature in Future Sight, Fleshwrither.

Transform

Transform is a keyword action that only appears on double-faced cards. Each transform card enters the battlefield with its front face up, and when certain conditions are met, the player turns the card over to its other face to transform it.

When the ability is used the player discards the card, then may search their deck for any card containing the indicated subtype and put it in their hand.^[5]: 135 It first appeared in Scourge as "Landcycling", indicating cards which could search for basic lands. Typecycling was redefined with the release of Future Sight to allow searching for other types of cards, and also appears in Alara block. Typecycling activates anything that would trigger on cycling.

Undying

When a creature with undying is put into a graveyard from the battlefield, if it had no +1/+1 counters on it, it is returned to the battlefield under its owner's control with a +1/+1 counter.^[5]: 150 Undying first appeared in Dark Ascension. Undying is very similar to persist.

Unearth

Unleash appears on red and black cards of the Cult of Rakdos in Return to Ravnica.^[18]

Vanishing

This ability is written Vanishing x. A permanent with vanishing enters the battlefield with x time counters on it. At the beginning of its controller's upkeep, a time counter is removed. When the last counter is removed, the card is sacrificed.^[5]: 143 Vanishing was introduced in Time Spiral and is a modification of fading which uses time counters to interact with other Time Spiral cards.

Ward

Whenever a permanent with ward becomes the target of a spell or ability an opponent controls, the ability is countered unless that player pays the associated Ward cost.^[5]: 131

Wither

Wither is a replacement ability that modifies damage. Nonlethal damage marked on a creature normally goes away at the end of the turn. However, whenever a source with wither deals damage to a creature, that creature receives a number of −1/−1 counters equal to the amount of damage dealt to it. When it deals damage to a player, that player will receive regular damage unlike infect.^[5]: 146 Wither was introduced in Shadowmoor.

Chroma

Chroma is an ability of a permanent or spell that checks for specific mana symbols of cards in specific zones. When a card with chroma is played, it will indicate a specified effect or characteristic-defining ability and repeat it for every color symbol in the checked zone.

Domain

Domain refers to an effect that may be stronger or weaker depending on the number of basic land types (Plains, Island, Swamp, Mountain, and/or Forest) among lands a player controls.

Enrage

Enrage is a creature-exclusive ability word, indicating abilities that trigger whenever that creature is dealt damage. It appears in Ixalan block on white, green and red Dinosaur creatures.

Fateful hour

Grandeur

Grandeur is an ability written as Discard another card named (name of card): (effect). This was designed as a means of reducing the drawback of drawing multiple copies of the same legendary permanent. This ability appears exclusively on timeshifted legendary cards from Future Sight.

Hellbent

Cards with the hellbent ability word have greater effects if their controller has no cards in their hand. Hellbent appears in Dissension and is associated with the Cult of Rakdos; many other cards pertaining to the Cult function better while their controller has fewer cards in hand.

Heroic

Cards with the heroic ability word gain an advantage when targeted with a spell. Although there are many heroic effects, the most common use of this mechanic is to give a creature a +1/+1 counter. This mechanic first appeared with creatures from the Theros block.

Imprint

Imprint is an ability word which only appears on artifacts and creatures. All cards with imprint have either an activated (Cost: Effect) or triggered ability which allows the player to exile a card to grant abilities to the artifact with imprint. Imprint was introduced as a keyword in the Mirrodin block and became an ability word in the Scars of Mirrodin block.

Join forces

Join forces is an ability word geared toward multiplayer variants. An effect denoted with join forces allows all players to contribute to it, usually by paying mana, though that effect might not be mutually beneficial . Join forces appears in Commander.

Kinship

Kinship is an ability word that appears in Morningtide. All cards with kinship are creatures that check, at the beginning of their controller's upkeep, the top card of that player's deck. If it shares a creature type with the creature that has the kinship ability, the player may reveal it for a bonus effect.

Landfall

Landfall is an ability word associated with bonuses given to players for playing lands. Landfall first appeared in Zendikar with abilities of the form Whenever a land enters the battlefield under your control, (effect). The follow-up set, Worldwake, introduced a modified form of landfall on instant cards written as If a land entered the battlefield under your control this turn, (effect).

Metalcraft

Cards with the metalcraft ability word gain an additional effect while their controller controls three or more artifacts. Metalcraft appears in the Scars of Mirrodin block and is associated with the Mirran faction.

Morbid

Cards with the morbid ability word gain an additional effect during a turn in which a creature died. Morbid was introduced in the Innistrad block.

Radiance

The radiance ability word denotes abilities that target one permanent, but affect all permanents of the same type that share a color with the target. Radiance appears in Ravnica: City of Guilds and is associated with the Boros Legion.

Raid

A card with raid gains an additional effect if their controller attacked the turn they are played. Raid is associated with the Mardu and appears in Khans of Tarkir. It has reoccurred as a pirate mechanic in Ixalan.

Rally

The "rally" mechanic was first introduced in the Battle for Zendikar set, and is a keyword given to the abilities of allies from the original Zendikar set. A creature with a rally ability triggers whenever an ally enters the battlefield under their control and gives some kind of bonus to all of that player's creatures, even non-ally creatures.

Sweep

Sweep is an ability word used on spells with effects which can be strengthened by returning any number of lands of a single basic land type to their owners' hands. Sweep only appears on four cards in Saviors of Kamigawa. Mark Rosewater has opined that labeling this mechanic with an ability word was "a mistake".^[27]

Threshold

This ability was originally written Threshold — ability. Whenever a player has seven or more cards in the graveyard, their cards gain any threshold abilities they might have. A player cannot activate an ability tied to threshold unless they have seven or more cards in the graveyard. Threshold appears in Odyssey block and on some timeshifted cards in Time Spiral.

With the release of Time Spiral, Threshold ceased to be a keyworded mechanic. It was redefined to be an ability word with no rules meaning.

Not all shifts were as simple as changing the reminder text to rules text; for example, Centaur Chieftain required more tinkering to preserve the original way the card worked.^[28]

Undergrowth

Undergrowth provides benefits depending on the number of creatures in the player's graveyard. This mechanic appears in Guilds of Ravnica and is associated with the Golgari Swarm.

Banding

Banding is an ability that has defensive and offensive functions. A defending player determines how combat damage is dealt by an opposing creature if at least one of the creatures blocking has banding (without banding, the attacking player determines this). An attacking player may form "bands" of creatures with banding, which may also include one non-banding creature. If one creature in the band becomes blocked, the whole band becomes blocked as well, whether or not the defender could block other creatures in the band. This can allow many small creatures to "gang up" on a single bigger creature that would survive blocking any one of these smaller creatures.

Banding appears primarily in white cards. Weatherlight was the last set to print cards with banding; Mark Rosewater has since indicated that the ability was retired because "[even] the top players in the world [...] were confused by banding."^[29]

Bury

The term bury or buried was used in some early sets, where it served as shorthand for a two-part effect: destroying a permanent, and preventing that permanent from regenerating. It is still functionally present in the game, with newer cards using a complete explanation for each part of the effect. (e.g. "Destroy target creature. It cannot be regenerated.")^[30] Bury is found only in sets prior to Tempest; all cards which contained the term have been issued new wording to use either a "destroy" or "sacrifice" effect.

Fear

Fear is an example of "retroactive keywording", meaning it was an ability that had existed long before it was given a keyword; its eponymous card, Fear, was in the original set Limited Edition Alpha. Creatures with fear cannot be blocked except by black creatures and by artifact creatures. Fear has almost always appeared on black creatures. Fear was replaced as a viable keyword by intimidate.^[31]

Intimidate

A creature with intimidate cannot be blocked except by artifact creatures and creatures that share a color with it. It first appeared in Zendikar. In 2009, intimidate was announced as an evergreen keyword to replace fear, though it did not appear in a Core Set until Hideous Visage was printed in Magic 2012. As with fear, intimidate appeared on predominantly black colors, but did appear on other colors, particularly red. With Magic Origins, intimidate was phased out and supplanted by menace.^[31]

Landhome

This ability is written as (land type) home . A creature with landhome may only attack a player who controls a land of the specified land type, and must be sacrificed if its controller does not control at least one land of that same type. The ability was present since the Limited Editions of the game, and was first keyworded in Mirage with Kukemssa Serpent . The keyworded ability was only printed on blue cards of the "islandhome" variety. The last card to be printed with a keyworded landhome ability was Manta Ray from Weatherlight.

Landhome is unique in that it is the only printed keyworded ability to later be retroactively removed from the rules. While cards which previously had landhome still feature the associated restrictions, they have been issued errata replacing the keyword "landhome" with rules text describing the abilities.

Landwalk

This ability is written as (Land type) walk. A creature with this ability can not be blocked while the defending player controls at least one land with the printed land type (e.g. a creature with swampwalk can not be blocked if the opponent has a swamp on the battlefield). This ability is somewhat rare, with swampwalk and plainswalk being the most and least common, respectively. Landwalk is not limited to the five basic lands; for example, cards with legendary landwalk, snow landwalk, and nonbasic landwalk have been printed. Landwalk was discontinued with Magic Origins.

Phasing

Phasing introduced a new rule to the game. Cards with the status "phased out" are treated as though they do not exist except for cards that specifically interact with phased-out cards. At the beginning of each player's turn, all permanents the player controls which have phasing become "phased out", along with anything attached to the phasing cards. Any cards the player controls which were phased out become "phased in" and return to the battlefield at the same time. Phasing in or out does not tap or untap the permanent. A token that phases out ceases to exist, while anything attached to it phases out and does not phase in on the token's controller's next turn. Phasing appears in the Mirage block. The earlier cards Oubliette and Tawnos's Coffin were reworded to use phasing as well for a time; however, these errata were removed in 2007.^[32]

Phasing returned on the card Teferi's Protection in The Vampiric Bloodlust Deck in Commander 2017.^[33] Additionally, rules for phasing changes with this release allowing tokens to return rather than ceasing to exist when phased out.^[34]

Regenerate

Regenerate represented two related keyword actions. An ability such as "Regenerate [this creature]" could be activated; in this context "regenerate" means "set up a regeneration shield", which protects the affected permanent from the next time it would be destroyed (either due to damage or to "destroy" effects). Instead of being destroyed, the permanent would become tapped and be removed from combat. The second keyword action refers to when this actually occurs: cards like Skeleton Scavengers have a delayed triggered ability that only triggers when the creature has a destroy effect prevented by its regeneration ability. This ability was generally found on creatures, though any permanent can be regenerated.

Shroud

A player or permanent with shroud cannot be the target of spells or abilities (even their own). While the keyword "shroud" was introduced in Future Sight, the ability itself existed long before, first appearing on Spectral Cloak; cards which featured this ability were all issued rules errata to have or grant "shroud". Creatures with shroud are most often on blue or green cards. It has been supplanted completely by the more flexible Hexproof.

Substance

Substance was a static ability with no effect which was never printed on a Magic card. It was originally created for the Magic: The Gathering Online release of Mirage, as a cycle of cards such as Armor of Thorns did not work as originally intended under the rules established with the release of 6th Edition. These cards were all enchantments that could be played as instants, but only lasted for one turn if played as an instant. Under the newer rules, the original wording would cause the enchantment to leave the battlefield before damage was removed from creatures. The creation of substance restored the cards' intended functionality.^[35] With the rule changes announced in July 2009,^[36] all cards edited to use this keyword were re-edited to no longer use it. The official text of such cards now refers to the cleanup step explicitly. This maintained the same functionality as the substance keyword, but without some unintended rules quirks.
