Scurrid Colony
A 2/2 with reach for two mana is a fine early blocker; a 4/4 with reach for the same cost is a beater that trades up and holds down the ground. The land count is the toggle between those two cards, and eight is high enough that the payoff arrives in the midgame rather than being free. That threshold does the work of a mana sink without asking for extra mana: you play it on turn two as a body and it upgrades itself later, no activation, no cards spent. Reach is the quiet part of the design. Squirrels read as tokens and chump fodder, so a creature that both climbs to 4/4 and swats fliers turns a tribe usually built for width into one that can actually contest the air. The whole thing sits in a long tradition of green two-drops that reward you for durdling toward a big board: the card is small when the game is small and large when the game has gone the way green wants it to.
