Dress up to three of your pieces (your king excepted) from the trunk, forever (purely decorative). Costumed pieces cannot be captured on your opponent's next turn: nobody hits an actor mid-scene.
You draft Costume Trunk in either mode. Activated: you choose when to use it, and using it is your move for that turn.
As a item card, it is a one-use consumable, drafted in either mode.
