This brilliant recycling loop lets you generate infinite mana and triggers by cycling your key creatures through the graveyard, all while Frostcliff Siege buffs your board with the Temur mode's power boost, trample, and haste. You fund the engine by tapping Selvala, Heart of the Wilds for a massive influx of mana, which is then converted by Thermopod into the red mana needed to keep things moving. Slimefoot and Squee acts as the ultimate recurring anchor, bringing itself and Selvala right back to the battlefield while simultaneously producing the fresh Saproling token required to pay for the recursion cost.
