Final Death

Unconditional exile at instant speed is one of black's oldest structural cravings, and the price here is bluntness: five mana buys a removal spell that answers anything with a toughness, indestructibility and regeneration included, at the cost of being the slowest way to do it. That trade is the whole design conversation. Black has always killed creatures cheaply if you accept riders (dead things come back, edicts let the opponent choose which creature dies, -X/-X shrinking effects like Disfigure or Bile Blight leave the biggest bodies standing), and every discount opens a hole to exploit. This spell refuses the discount and buys the clean answer instead: no "nonblack" clause, no power cap, no death trigger left on the board to loop or reanimate. Exile rather than destroy is what pays for the rate, closing off the graveyard-recursion escape hatch that makes cheaper black removal a temporary solution against the right decks. It is the spell you reach for when killing the creature is not enough and the creature simply has to be gone: a commander that keeps returning from the graveyard, an indestructible threat that shrugs off destruction effects, a value engine that profits from dying. The one thing it cannot overcome is the requirement to target: because the spell picks out a specific creature, genuinely hexproof threats stay out of reach. The design pays for everything except that. Deliberately overcosted, deliberately unconditional, and honest about the tradeoff it asks you to make.
