This looping engine transforms the raw materials of Spawning Pit into an overflowing cascade of mana and triggers, perfectly fueled by Jaheira, Friend of the Forest turning every token you control into a mana producer. Mondrak, Glory Dominus doubles the output of those newly spawned tokens so that every activation nets a surplus, all while Urabrask the Hidden ensures your fresh creations are instantly ready to tap for mana the moment they hit the battlefield. By continuously sacrificing those tokens back to Spawning Pit to reload its counters and feed the loop, you generate infinite enter-the-battlefield, death, and sacrifice triggers alongside boundless green mana.
