Hulkling, Burgeoning Bruiser

Most "grows with your board" green creatures reward going wide, counting bodies as they arrive. This 2/3 reverses the incentive: the counter only lands when a creature bigger than it shows up, so the trigger is a moving target that gets harder to hit as the bruiser grows. Early, almost anything you cast clears the bar. A few counters in, the body is a 4/5 or 5/6, and now only your top-end threats keep the engine turning. That self-tightening requirement is where the design lives, because it wants a curve stacked toward the top rather than a flat swarm: it punishes the mana-dork-and-tokens builds green usually leans on and rewards a deck that keeps deploying fatties. Vigilance is the quiet accelerant here, letting the growing body attack every turn without surrendering the blocking presence that a slow, counter-by-counter climb depends on to stay alive. The result is a green threat that plays less like a lord and more like a threshold engine, one where your own creatures compete against it to feed it, and where the reward scales precisely because the ceiling keeps rising.
