Song of Freyalise
Two turns of green acceleration, then a payoff that ends the game: that's the bargain this Saga strikes, and the structure is what separates it from a plain ramp spell. Chapters I and II hand every creature you control the ability to tap for any color, which means it isn't fixing your mana so much as turning your board into a mana engine. The wider your battlefield, the more it produces, and unlike a one-shot ritual it sticks around to do it twice. That sets up the third chapter, which converts the board you built into a board that wins: a +1/+1 counter spread across the team plus vigilance, trample, and indestructible for the turn. The progression rewards going wide before it ever asks you to swing, and the indestructible clause on the final chapter means the alpha strike survives the block-and-trade math most green decks fear. The any-color clause is the quiet hinge: it lets a green creature base power spells far outside green, so the acceleration phases double as a splash enabler before the payoff lands. The three chapters read as a coherent arc: fuel the board, fuel it again, then ask it to end the game. What most Sagas do with sequential removal or recursion, this one does with a ramp-to-overrun curve compressed into a single two-mana enchantment.
