From Archon Arcana - The KeyForge Wiki
Creatures are one of the basic card types in the game.
Creatures enter play exhausted and are placed in the front row of the active player’s play area. This row is referred to as the battleline. Creatures remain in play from turn to turn.
Creatures have a power value and may also have an armor value. Creatures can take damage, and if a creature takes damage equal to its power, it is destroyed.
Creatures can be used to fight, reap, or for their “Action:” or “Omni:” abilities (if any).
