Oran, Bane of Capashen

Flying
If your devotion to black and your devotion to
red are both exactly four, you may pay 4 life and
reveal Oran, Bane of Capashen from your hand.
When you do, destroy up to eight target colored
permanents. They can't be regenerated. Activate
this ability only once a game.
