A Tale of Tragedy

Spectacle {b}{r} (You may cast this spell for its spectacle cost rather than its mana cost if an opponent lost life this turn.)
Whenever a creature you control deals combat damage to a player, that player discards a card at random. If he or she can't, draw a card.
"Did you ever hear the tragedy of Darth Plagueis "the Wise"?"
— Chancellor Palpatine
