Threefold Thunderhulk

The whole engine hinges on a feedback loop the counter mechanic quietly builds: power scales the token count, the tokens are artifacts, and artifacts feed the sacrifice ability that adds more power. It enters as a 0/0 that survives only because it arrives with three +1/+1 counters, so a resolved copy is already a 3-power body making three Gnomes, and every attack repeats the count at whatever size the board has pushed it to. The sacrifice ability is where the loop tightens: the tokens it makes are the same artifacts it eats to grow, so it can cannibalize its own production to swell before the next attack trigger recounts. What is worth naming is how the card generates its own fuel and its own scaling engine off a single resource, with the only ceiling being how many two-mana activations you can afford. The colorless artifact framing matters, because it means the whole apparatus (the counters, the Gnome tokens, the sacrifice fodder) lives in any deck willing to spend seven mana, no color commitment attached. Most go-wide payoffs that also make their own tokens still need a separate anvil to convert bodies into value; this one folds the anvil, the fuel, and the payoff into a single creature.
