Gnarled Sage

A defensive body that quietly asks you to build around card advantage. The base 4/4 with reach is a plain enough wall, the kind of anchor a green deck already wants against fliers, but the conditional clause turns it into something a draw-two strategy can lean on: once you've seen two cards in a turn, it firms up to a 4/6 and starts attacking without dropping its guard. That vigilance line does the interesting work, because it resolves the usual treefolk tension. Big green defenders normally have to choose between holding the ground and pressing an advantage; here, on the turns your engine is running, it does both. The design leans on the "second card" as a soft threshold rather than a hard combo trigger, so it rewards steady card-flow (cantrips, extra draw steps, ramp into a draw spell) without demanding a specific enabler. Left alone, it's a fair rate for a defensive creature. Fed a stream of cards, it becomes a self-sustaining blocker that also closes games, a Druid that pays you back for the very thing your deck was already doing.
