Gnarlid Pack

The 2/2 for two is the floor, never the ceiling. Multikicker turns each spare into a permanent +1/+1 counter, making this a green mana sink that scales linearly from the moment you draw it: cast it early for a fair body, or hold it and dump six lands into it later for a beast that ends the game. The counters are the structural point. They sit on the creature rather than the spell, so they survive Stifle-style trickery on the cast, they stack with anything that doubles or moves +1/+1 counters, and they make the Gnarlid a legitimate home for proliferate and counter-matters payoffs rather than a vanilla beater that happens to be large. The open-endedness matters here: where the older kicker designs gave you a single bonus or none, multikicker has no cap, so the only ceiling is how much mana you are willing to commit on cast. That open-endedness is also the cost. Every point of size is paid in real time at sorcery speed, with no way to grow the body after it resolves, which suits a deck that floods the board with green mana and strands one that needs to hold up interaction. It is the cleanest expression of the "spend all your mana, get a proportional creature" idea: simple math, no text bloat, and a curve that quietly bends upward the longer the game runs.
