Undergrowth Champion

The damage-prevention clause is the whole engine, and it reframes what a counter means on this creature. Elsewhere a +1/+1 counter is just stats; here each one doubles as a charge that eats one source of damage outright, no matter how large, by peeling itself off instead of letting the body take the hit. That warps how removal reads against it: burn no longer kills, it merely shrinks, one counter per spell, so a Lightning Bolt that should be lethal only shaves a point of size, and a stacked board can demand three or four burn spells to clear. Best of all, the lands themselves resupply the shield, which means the creature and the deck's own engine push in the same direction: every fetch crack, every extra land drop, restocks the charge it spent blocking. The vulnerability is exact and worth naming because it is the entire counterplay. Strip the last counter (or keep one from ever landing) and it is a naked 2/2, dead to any two points like a normal creature its size; anything that deals no damage at all (bounce, exile, edicts, sacrifice) sidesteps the prevention completely. It is built to humiliate decks that win with burn and to reward decks stacked with land drops, and the gulf between how those two archetypes answer it is the axis the whole card sits on.
