You can flip a coin. If heads destroy all creatures on opponents' side of the field. If tails destroy all creatures on your side of the field and take damage equal to the number of creatures destroyed.

Spells you cast from your hand cost 1 less to cast.

{u}{u}{t}: Bring 1 creature from any graveyard to your side of the field if it was destroyed this turn.
