At the beginning of your upkeep, discard a card at random. If you discard a creature card this way, return it from your graveyard to the battlefield unless any player pays 5 life.
Kicker {1}{R} (You may pay an additional {1}{R} as you cast this spell.) Destroy target nonblack creature. It can't be regenerated. If Agonizing Demise was kicked, it deals damage equal to that creature's power to the creature's controller.
