Mage Tower Referee

A colorless artifact body that grows on multicolored spells is a small joke with a real payload: the creature has no color of its own, yet every gold spell you cast feeds it. The design lives in that reversal. Most multicolor payoffs are themselves multicolored, so the reward is gated behind the same mana requirements it asks you to meet; this one costs two generic and slots into any color combination, which means it counts your gold spells without competing for the pips that cast them. The growth is incremental rather than explosive, one counter per cast with no doubling, no bonus on toughness beyond the counter itself, and the 2/1 starting body reads as fragile until the counters start stacking. That fragility is the cost of the flexibility: it enters as a chump-tier target and only earns its keep in a deck genuinely built to chain multicolored spells, where a turn that resolves two or three gold cards leaves it a real threat instead of a two-drop that trades down. The construct type and the colorless cost are doing the quiet work here, letting a spell-count payoff live in shells that would never run a gold creature just to trigger it.
