Powerstone Fracture

Unconditional removal at two mana has always been priced with a leash, and this one attaches the leash to the graveyard's edge: the destroy effect hits any creature or planeswalker with no restriction on toughness, loyalty, or type, but you pay for that breadth by feeding an artifact or creature into the spell before it resolves. That additional cost is the whole balancing act. In a vacuum it looks punishing, since you are spending two cards to kill one; the design only makes sense in a deck already generating expendable bodies or artifacts as a byproduct of doing something else, where the sacrifice is closer to free than it looks. Token makers, treasure and powerstone engines, aristocrat shells that want death triggers anyway: for those, the sacrifice clause stops being a tax and becomes a second trigger. Black has a long lineage of edict and sacrifice-cost removal that turns the cost line into a value engine rather than a penalty, and this sits squarely in that tradition, trading the usual "you sacrifice, they choose" edict wrinkle for hard targeting at the price of committing your own permanent. The result is a spell that punishes decks trying to jam it as generic removal and rewards decks that were going to sacrifice something on that turn regardless.
