This engine relies on the unique recurrence of Squee, the Immortal to endlessly feed the sacrifice outlet Thermopod, generating an endless stream of mana and triggers. The transformation of Norman Osborn into Green Goblin is crucial here, as his Goblin Formula gives every nonland card in your graveyard mayhem, letting Squee be repeatedly cast right back from the graveyard for just its mana cost. Meanwhile, Teval, the Balanced Scale provides the necessary fuel and payoff by turning every card leaving the graveyard into a fresh Zombie Druid token to sacrifice alongside Squee, sustaining the loop indefinitely.
