Gaea's Will

Yawgmoth's Will wrote the mono-black rulebook for graveyard recursion two decades ago: pay a lump of mana, replay everything in the yard, exile the pile at cleanup. This is the green translation, and it does not copy the original straight. Where the black version demanded a hard sorcery-speed investment on the turn you wanted the payoff, suspend splits the cost from the moment. You pay a single green mana to slide it under four time counters, then wait: a counter comes off each of your upkeeps, so the effect fires on the fourth of your turns after suspending, and the play window opens for zero mana. That reframes the whole build-around. You are not saving toward one explosive turn; you are committing to an inevitability far in advance, then arriving on the payoff turn with an untapped board and a full graveyard behind it. The graveyard-exile clause does the same self-limiting work here that it always has: any card that would hit your graveyard this turn is exiled instead, so a spell you cast off the top of the yard can't be recast the same turn, and this is a combo detonation and not a repeatable engine. Everything hard about the card lives in the assembly. Stocking the yard, finding the mana to convert it, and having a way to close on the exact turn the timer expires is a demanding sequence, and only a shell already trying to turn a loaded graveyard into a single lethal chain has the pieces to pay it off.
