Burgeoning

The trick that makes this one mana worth playing is whose turn it works on. Acceleration in green has always paid a card and a setup cost: ramp creatures and Rampant Growth-style spells convert a card into a land on your own turn, at a tempo deficit you eat up front. This inverts the meter. By keying the trigger off opponents playing lands, it spends their turns building your manabase, and because the extra land enters from your hand as the trigger resolves, the acceleration arrives at instant speed without ever using your own land drop or sorcery window. The asymmetry is the whole design: you front-load nothing and let the table fund you, with the only governor being how many lands you can keep stocked in hand. That makes it a slow burn in a duel, where one opponent feeds it at a trickle, and a genuine engine when several opponents are each making land drops you get to mirror. It asks for a fat opening hand and rewards dumping the excess lands you couldn't otherwise have played yet, which is the inverse of how almost every other ramp card in the game wants you to sequence. A quiet, parasitic piece of acceleration that has aged into one of green's most efficient ways to pull ahead on mana without spending a turn doing it.
