Resolve As Much As You Can
From Archon Arcana - The KeyForge Wiki
While resolving a card ability, resolve as much of the ability as can be resolved, and ignore any parts of the ability that cannot be resolved.
Example: Aaron plays the card Anger (COTA 001), that reads “Play: Ready and fight with a friendly creature.”, and chooses his friendly Snufflegator (COTA 358) to resolve the ability on. However, the Snufflegator is already ready, so Aaron ignores that part of the ability and just uses his friendly Snufflegator to fight.
