Abominable Treefolk

Snow-matters payoffs live or die by how hard they lean on the deckbuilding tax, and this one asks for the whole subtheme in service of two returns: a body that scales with every snow permanent you control, and a tempo swing stapled to the front. The size clause is the honest half of the bargain: because snow permanents are almost entirely lands, the creature reads as a modest-sized attacker without any nonland snow support, and grows toward something genuinely threatening as the count climbs. Trample is the closer's insurance, because once the count is high enough, chump blockers stop buying time.

The enters-the-battlefield tap is what separates it from a vanilla snow beater. Tapping down an opponent's creature and holding it through their next untap step is a two-turn removal-of-a-blocker effect that lines up with the swing you were already planning: clear the biggest wall the turn it lands, and again the turn after. That tap-and-hold clause does the work a permanent-locking blue effect does, welded onto a growing green threat, without needing to recast anything to keep the wall down. The design commits fully to a mechanic that rarely gets a payoff this aggressive: rather than reward you for splashing a little snow, it demands the snow count be real, and pays you in both stats and combat math when it is.
