This clever loop turns Spawning Pit into a self-sustaining token engine by leveraging the mana-generating gift of Jaheira, Friend of the Forest. Because Elspeth, Storm Slayer doubles every token creation event, the single Spawn token you pay for actually yields a pair of them—leaving you with a net surplus after you tap them for green mana via Jaheira's static ability. You then feed those creatures right back into Spawning Pit to replenish its charge counters, fueling an infinite cycle of sacrifices and green mana. While Barbarian Class sits quietly in the background as an enchantment, its presence rounds out the board state for any Commander or Legacy deck looking to turn these endless triggers into a decisive advantage.
