This clever loop turns Spawning Pit into an engine that generates infinite green mana, sacrifices, and creature tokens by exploiting a compounding resource loop. Jaheira, Friend of the Forest bridges the gap by granting your newly spawned creatures the ability to tap for green mana, funding the {1} activation cost required to fuel Spawning Pit's second ability. Meanwhile, Exalted Sunborn supercharges the process with its replacement effect, doubling the number of tokens created each cycle so you net a profit of mana and counters with every iteration. Though Cyclops of Eternal Fury and Exalted Sunborn's other keywords don't directly feed the loop, their presence—alongside Exalted Sunborn's warp ability—completes the mechanical ensemble powering this Commander-legal setup.
