Abomination, Irradiated Brute
The math is the whole engine here, and it counts every point your Gamma and Villain creatures push through, itself included. A 4/4 with trample for four mana is a body you would shrug at in any color; what changes the calculus is that this creature grows by whatever combat damage the tribe deals to a player, so a single connecting swing converts one-for-one into permanent counters. That reframes the deckbuilding problem: the payoff wants a wide, evasive, or unblockable board that reliably lands hits, and it wants the biggest of those hits to happen while it is on the battlefield. Point a swarm at an open opponent and the counters accrue as each attacker connects, one trigger at a time across the combat step. Because they are +1/+1 counters, they stack with the trample it already carries, turning the recipient into a finisher that spills over blockers on the following turn: a bruiser that leaves less and less behind. The trample keyword pulls quiet double duty here, both feeding the ability when this creature connects through a chump and cashing the accumulated counters into damage that gets home. It is a payoff piece wearing the costume of a beater, and it snowballs fastest when opponents leave any of your creatures unanswered.
