This elegant loop harnesses the relentless copying power of Followed Footsteps to keep your engine running indefinitely. Each upkeep, the Aura spawns a fresh Greenwarden of Murasa, whose enter-the-battlefield ability plucks Walk the Aeons straight out of your graveyard. By casting Walk the Aeons with its buyback cost—sacrificing the very Islands you tapped for mana—you immediately secure an extra turn, feeding the spell right back to the Greenwarden's recursion. The result is an unbreakable chain of infinite turns and an army of botanical guardians to seal the game.
