Embrace Oblivion

Black rarely gets to kill creatures for a single mana without strings attached, and the string here is a familiar one paid in a new denomination: you sacrifice an artifact or a creature to fire it off. That additional cost is what buys the color a clean, unconditional Destroy at the bottom of the curve, and it recasts the spell as a conversion rather than a tempo play. You are not spending a card to answer a threat so much as spending a permanent you already control, which slots naturally into any deck that manufactures expendable bodies: token makers, treasure and clue generators, aristocrat shells that want things dying anyway. The target line quietly widens the job description too, reaching Spacecraft alongside creatures, so the spell answers a class of permanent that most cheap black removal simply cannot touch. The design tension is the honest one for a sacrifice-cost removal spell: it is superb when you have fodder to feed it and awkward when your board is bare, since the cost is not optional and cannot be paid with life or mana. Locking the price to a permanent you already have on hand is what lets the rate run this hot without breaking. It rewards decks built to overflow with disposable permanents and punishes the ones reaching for premium removal off an empty board, which is exactly the line a one-mana kill spell has to walk to stay legal.
