Restrictions
From Archon Arcana - The KeyForge Wiki
Many abilities include specific instructions that limit when or how a card may be played or used.
If a card includes one or more play restrictions, the card cannot be played unless all play restrictions are met.
If a card includes multiple different restrictions on how it can be used, all such restrictions must be observed.
If two restrictions are limiting the exact same effect or game step, the more restrictive of the two applies.
