Overwhelming Remorse

Unconditional exile at instant speed has always been priced defensively, and the sticker cost here is five mana for an answer that leaves nothing behind: no death trigger to farm, no body to reanimate, no counter to reset. What moves that rate is the graveyard clock. Every creature card in your bin knocks a generic off the cost, so the spell rewards the exact game state most exile effects are trying to climb out of. A control deck grinding through a long game will rarely find it cheap; a black midrange or aristocrats shell that has been trading bodies all game turns it into a two- or even one-mana instant that cleanly answers the scariest creature or planeswalker on the board. The design threads a familiar tension in black removal: black gets the cleanest answers in the game, but pays for them, in life (the old edict and drain lines) or in tempo. Here the tax is deferred rather than paid up front, converting the graveyard from a resource you spend into a discount you accumulate. It scales with the same self-mill and sacrifice engines a black deck was already running, so its floor is a slow, honest exile card whose price ticks downward one increment at a time as the game does the work for you. The restriction that keeps it fair is the target line: creatures and planeswalkers only, never lands, artifacts, or enchantments, so the discount buys efficiency, not reach.
