Banish

Codex Entry:

 * While the creature is outside of the Arena, it is still considered “in play”. It is out of range and LoS of all other objects, even other objects that are outside of the Arena. It can still be affected by its own traits and abilities, and by cards attached to it. Abilities which look for things happening in play, but don’t have a specific range or require LoS, still work. (For instance, a banished Valshalla, Lightning Angel can still gain Wrath tokens.) Since its action marker’s status can’t change, it won’t reset its action marker during the Reset Phase. Thus, it will return to the Arena with its action marker in the same state that it was in when Banish first resolved.
