Masterful Replication

Six mana at instant speed buys one of two very different outcomes, and the gap between them is the whole design. The first mode is a flat, honorable Golem factory: two 3/3 bodies flashed in as a combat surprise or a chump-block insurance policy, the sort of effect that has occupied blue's high-end token slot for a long time. The second mode is the one the card is actually built around, and it only functions if your board is already an artifact ecosystem: point at one artifact you control and stamp every other artifact you control into a copy of it until end of turn. That clause turns a shelf of Signets and mana rocks and utility artifacts into a temporary army of your single most valuable one, which is why the effect is priced at six and gated behind a board state you have to assemble first. The elegance is that the two halves address opposite game states with the same card. Behind on board and short on artifacts, you take the Golems and treat this as a modest instant-speed swing. Ahead, with a wide artifact base and a copy-worthy target, the second mode is an explosive one-turn multiplier that no fair deck plays toward. Blue rarely gets to make creatures and rarely gets to go this wide off a single spell; the modality is what lets it do both without either half being oppressive on its own.
