Finale Cannon

Spectacle {1}{b}{r} (You may cast this spell for its
spectacle cost rather than its mana cost if an opponent
lost life this turn.)
Whenever one or more creatures crew Finale
Cannon, sacrifice one of them at the beginning
of the next end step. When you do, Finale
Cannon deals damage equal to the sacrificed
creature's power to target opponent or creature
you don't control chosen at random.
