This clever loop relies on the seamless recursion of Squee, the Immortal, which can be cast repeatedly from your graveyard as long as you have the mana. Thermopod acts as your sacrifice outlet and mana engine, turning each iteration into red mana while sending Squee back to the graveyard. Meanwhile, Blight Mound watches from the sidelines, steadily capitalizing on Squee's departures by generating Pest tokens that you can also feed to Thermopod. Finally, Norman Osborn transformed into Green Goblin acts as the ultimate enabler, making your spells cast from the graveyard cost {2} less so that Squee's casting cost drops to a manageable price, fueling this endless cycle of life and sacrifice.
