E: If your attack deals damage, turn it face down in your card pool. Face down cards cannot go to your momentum.

F Commit: Face down cards in your card pool are not cleared as normal until the End Phase of your next turn (they stay in your card pool).

R Discard up to 2 face down cards from your card pool: After your Combat Phase begins, attacks you play this turn get +X damage. X equals the number of face down cards you discarded from your card pool.
