Demonic Appetite

A single black mana buys +3/+3, a violent rate for a one-drop Aura, and the recurring upkeep sacrifice is the bill that comes due. The structure forces a particular kind of deck: one with a steady stream of bodies to feed the trigger, ideally creatures that want to die anyway. Read straight, it looks like a downside enchantment, a holdover from an era when cheap Auras routinely came with a tax attached to keep their stats in check. But the sacrifice clause is not purely a cost; it is an engine input. Pair the Aura with token generators or with creatures carrying death triggers and the forced sacrifice becomes a free upkeep trigger you never pay mana for, turning a liability into a recurring spark for aristocrats payoffs. The danger is that the trigger asks for a creature you control without offering a way to aim it: you cannot redirect the sacrifice to an opponent, and the body you most want to keep, the one wearing the +3/+3, is fair game when the cupboard is bare. If the enchanted creature is itself the only thing on board, the Aura goes with it to the graveyard, and there is no clause here to move it or buy it back. That inflexibility is what keeps the rate honest: in a deck built to feed it, the upkeep is fuel; in a deck without an outlet, it is a slow self-cannibalizing tax.
