Ultima Weapon

Seven to cast, seven to move, and every attack a mandatory murder: this is Equipment built for the point where the numbers stop pretending to be fair. The +7/+7 is the loud part, but the attack trigger is the real engine. Because it destroys a creature every time the equipped body swings, the card taxes the opponent's board on a clock rather than all at once, stripping away a potential blocker before damage even happens and turning any evasive creature into a repeatable removal spell bolted to a hard-hitting threat. The steep costs are what keep it from being a flat auto-win: you pay seven to deploy the Equipment, then seven again to attach it, so the true entry point is a fourteen-mana commitment before a single attack resolves, and re-equipping to a fresh body after your carrier eats removal costs another seven. That equip tax is the pressure valve, forcing a choice between casting other threats and pouring everything into one must-answer creature. The destroy clause targets a creature an opponent controls with no protection built in, so hexproof, indestructibility, and instant-speed sacrifice all blunt it, and the trigger fires only on attack, never on the equip itself. The card wants a deck that can already put a creature into the red zone and wants that swing to end things outright.
