Wizards of the Coast 27 Jan 2026

If a triggered ability is linked to a second ability, additional instances of that triggered ability are also linked to that second ability. If the second ability refers to "the exiled card," it refers to all cards exiled by instances of the triggered ability.

Wizards of the Coast 27 Jan 2026

In some cases involving linked abilities, an ability requires information about "the exiled card." When this happens, the ability gets multiple answers. If these answers are being used to determine the value of a variable, the sum is used. For example, if Elite Arcanist's enters ability triggers twice (probably because it entered as a Ninja due to another effect), two cards are exiled. The value of X in the activation cost of Elite Arcanist's other ability is the sum of the two cards' mana values. As the ability resolves, you create copies of both cards and can cast none, one, or both of the copies in any order.

Wizards of the Coast 27 Jan 2026

Splinter's first ability doesn't copy the triggered ability; it just causes the ability to trigger an additional time. Any choices made as you put the ability onto the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution, such as whether to put counters on a permanent, are also made individually.

Wizards of the Coast 27 Jan 2026

Triggered abilities use the word "when," "whenever," or "at." They're often written as "[Trigger condition], [effect]." Some keyword abilities are triggered abilities and will have "when," "whenever," or "at" in their reminder text.

Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryWUBPlayers write colors as letters: W for white, U for blue, B for black. Blue is U because B was already taken by black.Blink/FlickerBlink decks briefly remove their own creatures from play and return them at once, so every 'when this enters' ability happens again.
