An object may have multiple abilities. If the object is represented by a card, then aside from certain defined abilities that may be strung together on a single line (see rule 702, “Keyword Abilities”), each paragraph break in a card’s text marks a separate ability. If the object is not represented by a card, the effect that created it may have given it multiple abilities. An object may also be granted additional abilities by a spell or ability. If an object has multiple instances of the same ability, each instance functions independently. This may or may not produce more effects than a single instance; refer to the specific ability for more information.
Aura spells are always targeted. An Aura’s target is specified by its enchant keyword ability (see rule 702.5, “Enchant”). The target is chosen as the spell is cast; see rule . An Aura permanent doesn’t target anything; only the spell is targeted. (An activated or triggered ability of an Aura permanent can also be targeted.)
Some keyword abilities, such as equip and modular, represent targeted activated or triggered abilities, and some keyword abilities, such as mutate, cause spells to have targets. In those cases, the phrase “target [something]” appears in the rule for that keyword ability rather than in the ability itself. (The keyword’s reminder text will often contain the word “target.”) See rule 702, “Keyword Abilities.”
A player who has a card with suspend in their hand may exile that card. This is a special action. A player can take this action any time they have priority, but only if they could begin to cast that card by putting it onto the stack. See rule 702.62, “Suspend.”
A player who has chosen a companion may pay {3} to put that card from outside the game into their hand. This is a special action. A player can take this action any time they have priority and the stack is empty during a main phase of their turn, but only if they haven’t done so yet this game. (See rule 702.139, “Companion.”)
A player who has a card with foretell in their hand may pay {2} and exile that card face down. This is a special action. A player may take this action any time they have priority during their turn. See rule 702.143, “Foretell.”
A player who has a card with plot in their hand may exile that card. This is a special action. A player can take this action any time they have priority during their own turn while the stack is empty. See rule 702.170, “Plot.”
Some spells and abilities have additional costs. An additional cost is a cost listed in a spell’s rules text, or applied to a spell or ability from another effect, that its controller must pay at the same time they pay the spell’s mana cost or the ability’s activation cost. Note that some additional costs are listed in keywords; see rule 702.
Some spells have alternative costs. An alternative cost is a cost listed in a spell’s text, or applied to it from another effect, that its controller may pay rather than paying the spell’s mana cost. Alternative costs are usually phrased, “You may [action] rather than pay [this object’s] mana cost,” or “You may cast [this object] without paying its mana cost.” Note that some alternative costs are listed in keywords; see rule 702.
Hexproof
Hexproof is a static ability.
“Hexproof” on a permanent means “This permanent can’t be the target of spells or abilities your opponents control.”
“Hexproof” on a player means “You can’t be the target of spells or abilities your opponents control.”
“Hexproof from [quality]” is a variant of the hexproof ability. “Hexproof from [quality]” on a permanent means “This permanent can’t be the target of [quality] spells your opponents control or abilities your opponents control from [quality] sources.” A “hexproof from [quality]” ability is a hexproof ability.
Any effect that causes an object to lose hexproof will cause an object to lose all “hexproof from [quality]” abilities. Any effect that allows a player to choose a creature with hexproof as a target as though it didn’t have hexproof will allow a player to choose a creature with a “hexproof from [quality]” ability. Any effect that looks for a card with hexproof will find a card with a “hexproof from [quality]” ability.
“Hexproof from [quality A] and from [quality B]” is shorthand for “hexproof from [quality A]” and “hexproof from [quality B]”; it behaves as two separate hexproof abilities.
“Hexproof from each [characteristic]” is shorthand for “hexproof from [quality A],” “hexproof from [quality B],” and so on for each possible quality the listed characteristic could have; it behaves as multiple separate hexproof abilities.
Multiple instances of the same hexproof ability on the same permanent or player are redundant.
If multiple sources with lifelink deal damage at the same time, they cause separate life gain events (see rules 119.9–10).
Any time you have priority, you may turn a face-down permanent you control with a morph ability face up. This is a special action; it doesn’t use the stack (see rule 116). To do this, show all players what the permanent’s morph cost would be if it were face up, pay that cost, then turn the permanent face up. (If the permanent wouldn’t have a morph cost if it were face up, it can’t be turned face up this way.) The morph effect on it ends, and it regains its normal characteristics. Any abilities relating to the permanent entering the battlefield don’t trigger when it’s turned face up and don’t have any effect, because the permanent has already entered the battlefield.
Generic mana in the sacrificed permanent’s mana cost reduces generic mana in the spell’s total cost. Colored and colorless mana in the sacrificed permanent’s mana cost reduces mana of the same type in spell’s total cost, and any excess reduces that much generic mana in spell’s total cost. (See rule 118.7.)
Miracle is a static ability linked to a triggered ability. (See rule 603.11.) “Miracle [cost]” means “You may reveal this card from your hand as you draw it if it’s the first card you’ve drawn this turn. When you reveal this card this way, you may cast it by paying [cost] rather than its mana cost.”
Any time you have priority, you may turn a face-down conspiracy card you control in the command zone face up. This is a special action. Doing so will reveal the chosen name. See rule 116.2j.
Exploit
Exploit is a triggered ability. “Exploit” means “When this creature enters, you may sacrifice a creature.”
A creature with exploit “exploits a creature” when the controller of the exploit ability sacrifices a creature as that ability resolves.
Menace
Menace is an evasion ability.
A creature with menace can’t be blocked except by two or more creatures. (See rule , “Declare Blockers Step.”)
Multiple instances of menace on the same creature are redundant.
Renown
Renown is a triggered ability. “Renown N” means “When this creature deals combat damage to a player, if it isn’t renowned, put N +1/+1 counters on it and it becomes renowned.”
Renowned is a designation that has no rules meaning other than to act as a marker that the renown ability and other spells and abilities can identify. Only permanents can be or become renowned. Once a permanent becomes renowned, it stays renowned until it leaves the battlefield. Renowned is neither an ability nor part of the permanent’s copiable values.
If a creature has multiple instances of renown, each triggers separately. The first such ability to resolve will cause the creature to become renowned, and subsequent abilities will have no effect. (See rule )
Awaken
Awaken appears on some instants and sorceries. It represents two abilities: a static ability that functions while the spell with awaken is on the stack and a spell ability. “Awaken N—[cost]” means “You may pay [cost] rather than pay this spell’s mana cost as you cast this spell” and “If this spell’s awaken cost was paid, put N +1/+1 counters on target land you control. That land becomes a 0/0 Elemental creature with haste. It’s still a land.” Casting a spell using its awaken ability follows the rules for paying alternative costs in rules and –h.
The controller of a spell with awaken chooses the target of the awaken spell ability only if that player chose to pay the spell’s awaken cost. Otherwise the spell is cast as if it didn’t have that target.
Devoid
Devoid is a characteristic-defining ability. “Devoid” means “This object is colorless.” This ability functions everywhere, even outside the game. See rule .
Ingest
Ingest is a triggered ability. “Ingest” means “Whenever this creature deals combat damage to a player, that player exiles the top card of their library.”
If a creature has multiple instances of ingest, each triggers separately.
Myriad
Myriad is a triggered ability that may also create a delayed triggered ability. “Myriad” means “Whenever this creature attacks, for each opponent other than defending player, you may create a token that’s a copy of this creature that’s tapped and attacking that player or a planeswalker they control. If one or more tokens are created this way, exile the tokens at end of combat.”
If a creature has multiple instances of myriad, each triggers separately.
Surge
Surge is a static ability that functions while the spell with surge is on the stack. “Surge [cost]” means “You may pay [cost] rather than pay this spell’s mana cost as you cast this spell if you or one of your teammates has cast another spell this turn.” Casting a spell for its surge cost follows the rules for paying alternative costs in rules and –h.
Skulk
Skulk is an evasion ability.
A creature with skulk can’t be blocked by creatures with greater power. (See rule , “Declare Blockers Step.”)
Multiple instances of skulk on the same creature are redundant.
Emerge
Emerge represents two static abilities that function while the spell with emerge is on the stack. “Emerge [cost]” means “You may cast this spell by paying [cost] and sacrificing a creature rather than paying its mana cost” and “If you chose to pay this spell’s emerge cost, its total cost is reduced by an amount of generic mana equal to the sacrificed creature’s mana value.” Casting a spell using its emerge ability follows the rules for paying alternative costs in rules and –h.
Emerge from [quality] is a variant of emerge. “Emerge from [quality] [cost]” means “You may cast this spell by paying [cost] and sacrificing a [quality] permanent rather than paying its mana cost” and “If you pay this spell’s emerge cost, its total cost is reduced by an amount of generic mana equal to the sacrificed permanent’s mana value.”
You choose which permanent to sacrifice as you choose to pay a spell’s emerge cost (see rule ), and you sacrifice that permanent as you pay the total cost (see rule ).
An ability that reads “[This permanent] escapes with [one or more of a kind of counter]” means “If this permanent escaped, it enters with [those counters]” That ability may have a triggered ability linked to it that triggers “When it enters this way.” (See rule 603.11.) Such a triggered ability triggers when that permanent enters the battlefield after its replacement effect was applied, even if that replacement effect had no effect.
Companion is a keyword ability that functions outside the game. It’s written as “Companion—[Condition].” Before the game begins, you may reveal one card you own from outside the game with a companion ability whose condition is fulfilled by your starting deck. (See rule .) Once during the game, any time you have priority and the stack is empty, but only during a main phase of your turn, you may pay {3} and put that card into your hand. This is a special action that doesn’t use the stack (see rule 116.2g). This is a change from previous rules.
Exiling a card using its foretell ability is a special action, which doesn’t use the stack. See rule 116, “Special Actions.”
Any time you have priority, you may turn a face-down permanent you control with a disguise ability face up. This is a special action; it doesn’t use the stack (see rule 116). To do this, show all players what the permanent’s disguise cost would be if it were face up, pay that cost, then turn the permanent face up. (If the permanent wouldn’t have a disguise cost if it were face up, it can’t be turned face up this way.) The disguise effect on it ends, and it regains its normal characteristics. Any abilities relating to the permanent entering the battlefield don’t trigger when it’s turned face up and don’t have any effect, because the permanent has already entered the battlefield.
Exiling a card using its plot ability is a special action, which doesn’t use the stack. See rule 116, “Special Actions.”
