Matsu-Tribe Birdstalker

The combat-damage trigger here is the interesting part: it doesn't just remove a blocker from one fight, it locks the creature down through its controller's next untap step, so the body it bites stays tapped for an entire turn cycle. That turns a 2/2 into a recurring tempo engine in a green deck built around persistent attacks, freezing a defender on the first swing and walking past it on the second. The reach activation is the answer to the obvious objection that a ground-bound 2/2 has nothing to bite in the air; spend a green mana and it can block fliers, and because the tap-down trigger fires on any combat damage to a creature, blocking is itself a way to disable an attacker for a full rotation. The cost structure is deliberately back-loaded: nothing happens until damage connects, which keeps the rate honest and asks the green deck to invest in making the attack land (trample partners, evasion, removal for the better blocker) rather than handing it value on cast. It is a Snake Warrior Archer carrying an Archer's reach as an ability rather than a printed keyword, a design that wants to be in a creature-heavy board where freezing the opponent's best blocker compounds turn over turn.
