Centaur Rootcaster

Ramp gated behind connecting in combat is a strange place to put a fixing engine, and that gate is the whole reason this design stays modest. A 2/2 for four mana that has to survive a turn and then land a hit before it does anything is asking a lot in a green deck that already wants to be deploying threats. When it works, the payoff is real: a basic onto the battlefield each combat compounds toward something, and the tapped clause means the land does not help the turn it arrives, only the turns after. But the conditional structure puts it a tier below the mana creatures that ramp on entry or on tap, the ones green has always preferred because they pay out immediately and do not invite a blocker to trade. The flavor of a druid steering the battle toward its own growth is intact, and as a green common-tier engine it fills the slot for a creature that turns aggression into long-game inevitability. The trouble is that decks built to win combat usually do not need the extra land, and decks that need the land usually cannot win combat reliably enough to fire the trigger.
