Primal Growth

The interesting part is what kicker asks you to pay: a creature you no longer need. Unkicked, this is a Rampant Growth that puts a basic onto the battlefield, fine and unremarkable. Kicked, it fetches two basics for the price of feeding a creature to the spell, which reframes the whole exchange. It rewards a board that has already done its work: a leftover token, a tapped-out attacker, a mana dork whose only remaining job is to become more lands. Because the sacrifice is paid as an additional cost when the spell is cast, the creature is gone before its controller can be denied a death payoff and before an opponent gets a window to respond to the conversion. That makes the sacrifice usable as an aristocrat-style outlet on your own main phase: you decide which body cashes out, and the trigger resolves on the way to two lands and the deck-thinning you wanted. As a fixing-and-acceleration spell it is colorless in ambition and green in execution, asking only that you have something to spare. In a shell where you usually do, the kicker reads as upside rather than a tax, which is exactly why kicker was the right mechanic to hang the second land on: the spell stays castable when your board is empty and scales when it is not, without ever forcing the trade.
