Gaea's Courser

The 4/5 body arrives without strings, but the draw only fires on attack, and only once three or more creature cards sit in your graveyard. That condition is what keeps the rate honest: it asks a green deck to spend its early turns dying, blocking, and trading bodies before the Courser pays out, which is exactly the kind of attrition green midrange tends to fall into anyway. The trigger checks on the declare-attackers step, so it draws whether or not the attack connects, but the payoff is tied to swinging, not defending; a stalled position with three dead creatures in the yard draws nothing while the Courser holds down blocking duty. Green rarely gets repeatable card draw stapled to a creature this durable, and the design here is deliberately conditional: not an engine you assemble around, but a recurring bonus a grindy creature deck earns as a natural consequence of playing the long game. The body blocks most of what a fair deck fields and outlives spot removal aimed at smaller threats, giving the graveyard clause time to come online across multiple combats. The reward scales with how the game was already going: behind on the board, it is a plain 4/5; ahead and attacking with a stocked yard, it refills your hand every time it declares.
