Headsplitter

Most Equipment sits inert on the battlefield until you spend mana to attach it, which is the tax the whole card type pays for permanence: it survives creature removal, so it costs you a turn to get going. This one refuses that bargain by manufacturing its own bearer. Entering the battlefield produces a 1/1 black Assassin with menace and immediately buckles the axe onto it, so the two-mana investment reads as a 2/1 menace body that leaves a reusable +1/+0 buff behind when the token dies. That token is the point. It gives you a self-contained threat off a single cast, and because the Equipment persists, killing the creature only costs you the 1/1: the axe waits for the next body, cheap to move at equip . The menace matters more than the modest power bump, since a 2/1 that must be double-blocked pressures an opponent's board math in exactly the way a lone one-drop cannot. Structurally it belongs to the small family of Equipment that arrives pre-attached, folding the summon-and-suit-up sequence into one card so you are never left holding a buff with nothing to hold it. The flavor does honest work too: the weapon makes an assassin, the assassin carries the weapon, and when the assassin falls the blade is simply picked up again.
