Mm'menon, Uthros Exile

The trigger fires on artifacts entering, but the counter doesn't have to land on Mm'menon; the ability reads "target creature," which is the design decision doing all the work. Most artifact-payoff creatures reward you for filling your own stat line or churning out tokens. This one converts every artifact drop into a modular pump you can steer, spreading counters across a board, feeding a lone evasive threat, or stacking a creature until it clears a combat math problem. Because the counters are permanent and untethered from the source, the card scales with cadence rather than mass: a deck that plays cheap artifacts across multiple turns gets a slow, compounding board buff rather than one explosive swing. The 1/3 flyer body is deliberately unassuming, a survivable engine piece rather than a clock, which frames the card as an accumulator you protect rather than a beater you race with. What makes the counter placement matter strategically is the target flexibility at instant speed of the trigger: an artifact flickered or flashed in during combat can grow a blocker or an attacker mid-step, turning artifact velocity into a combat trick you didn't have to hold up mana for. It sits in the Izzet artifact tradition of turning cheap noncreature spells and permanents into incremental advantage, but it commits that advantage to bodies rather than cards, which is the less-explored half of that color pair's toolkit.
