Submerge — {u}{u} (You may cast this card for its Submerge cost. If you do, put it on the battlefield face down as a 1/1 creature with protection from red. Turn it face up any time it blocks or becomes blocked.)
When this card is turned face up, create a 3/1 blue Merfolk creature token and have it fight target creature you don't control.
