Spore Burst

A fixed exchange rate sits at the heart of this: one Saproling per basic land type among your lands, with a hard ceiling of five if you can assemble Plains, Island, Swamp, Mountain, and Forest. That ceiling is exactly why a four-mana green sorcery can give away this many bodies without breaking, and Domain is the ability word that makes diversity the toll. The mechanic punishes green's most natural manabase: a pile of Forests yields a single token, an embarrassing return for the spell, while a five-color or dual-typed land suite cashes out for a respectable board. The greed is paid up front, several turns earlier, when you chose to splash colors or run lands you would not otherwise want; the spell itself just reads back the answer. Among the Domain payoffs, this is the green token-swarm cousin to the burn and life-drain effects that share the keyword, each rewarding manabase ambition in proportion to how reckless you were willing to be. Saprolings are the correct fodder for the job: cheap green chaff that feeds sacrifice outlets, soaks removal, and scales into something lethal through the various Saproling lords and overrun effects that have accreted around the tribe over the years. The card never asks more mana than the floor demands; the difference between failure and a full table is settled entirely in deckbuilding, before the spell is ever cast.
