A cantrip that never quite goes to waste: pay one and sacrifice it for a card, and you've spent a slot doing the least a card can do while still doing something. The real design lives in the second mode, which turns the same artifact into a delayed combat instrument. For three mana (one of them white) and a sacrifice at sorcery speed, it hands a creature +2/+2 and flying and replaces itself, so an attacker becomes an evasive threat and your card count stays even. That sorcery-speed clause is the discipline that keeps the pump from being a blowout: no ambush blocks, no end-of-combat surprise, no holding it up as a trick. You commit to the swing before you know how it resolves. This is the equipment-adjacent lineage boiled down to its cheapest form, a one-mana permanent that sits on the board as a promise of two futures and asks you to pick one when the game tells you which it needs. The floor is the reason it makes the deck: colorless to cast, playable in anything, and if the aggressive plan never comes together it simply cashes out for a fresh card on a turn you have the mana to spare, keeping your hand whole rather than trading down.
