(Redirected from Card Ability)

An ability is the special game text a card contributes to the game.

Unless an ability explicitly references an out-of-play area (such as a hand, deck, archives, or discard pile), that ability can only interact with cards that are in play. Abilities that interact with a card after it is destroyed can interact with that card while it is in an out-of-play zone that is not hidden.

Abilities on a creature, artifact, or upgrade are only active (and can only be resolved) while that card is in play, unless the ability explicitly references being used from an out-of-play area. Once an ability on a card has started to resolve, that ability will finish resolving even if the card leaves play.

If resolving part of the instructions of a card ability causes other card effects to begin to resolve, resolve those other card effects before continuing to resolve the instructions of the first card.

KeyForge Master Rulebook v17.3 March 2024


There are currently no cards that force the non-active player to make any decisions. According to FFG, "The 'unless otherwise specified' language of card abilities was included more for future-proofing purposes in case there was a strange interaction between cards that would instruct the non-active player to make a decision."
