This ingenious engine uses Thermopod as a reliable sacrifice outlet that instantly converts your creatures into red mana while granting the haste needed to keep the loop moving, a quality neatly complemented by Kratos, God of War and its passive haste-granting aura. By utilizing Slimefoot and Squee's activated ability, you can pull both the legendary plant-fungus and Selvala, Heart of the Wilds straight out of your graveyard and back onto the battlefield. Every time Slimefoot and Squee returns, its enter-the-battlefield trigger creates a Saproling token to fuel further sacrifices, while Selvala, Heart of the Wilds taps for a massive influx of colored mana to fund the entire repeating cycle.
