Menace\nWhen Cemetery Desecrator enters or dies, exile another card from a graveyard. When you do, choose one —\n• Remove X counters from target permanent, where X is the mana value of the exiled card.\n• Target creature an opponent controls gets -X/-X until end of turn, where X is the mana value of the exiled card.
