Gimbal, Gremlin Prodigy

The reward here isn't for making tokens; it's for making different tokens. That end-step Gremlin scales off differently named artifact tokens, which quietly reorients how you build the deck: a pile of ten identical Thopters counts once, but a Treasure, a Clue, a Food, and a Powerstone each add to the pile. The counter math punishes the obvious go-wide plan and rewards a token base that looks more like a scavenger's collection than an army, which is a genuinely unusual axis to build a green-blue-red artifact deck around. The trample rider is the closer: a swarm of artifact creatures that ignores chump blockers turns every incidental token into damage, and the Gremlins the card manufactures arrive pre-buffed rather than as empty 0/0 fodder, so the engine feeds its own board without needing an anthem effect to keep the tokens alive. A diversity-counting counter engine plus evasion for the whole artifact side gives this commander a different pull than the usual "make a token each turn" build: it asks for a deckbuilding constraint most token strategies actively avoid, prizing variety over volume.
