Court Homunculus

The conditional that turns a one-mana 1/1 into a one-mana 2/2 is doing exactly one job: rewarding a deck built dense with artifacts, with the smallest possible condition. There is no toolbox here, no recursion, no late-game scaling; the bonus caps at +1/+1 and asks only that you control one other artifact, which is the lowest bar an affinity-style payoff can set. That low bar is the whole point. As an artifact creature itself, it counts toward everyone else's metalcraft and affinity thresholds while it waits for its own, so the card is both an enabler and a payoff in the same body. The design sits at the cheap end of the white-weenie-meets-artifacts line of creatures: it wants to attack as a 2/2 and trade into bigger bodies, and it gives that aggressive curve a creature that does not get worse if you draw it late, because by then the artifact you need is already on the board. The failure case is the part nobody mentions: in a deck without artifacts, you are paying white for a 1/1, and the card knows it. The reward is real only when the deckbuilding has already paid for it.
