Resolve both Slimefoot abilities, creating four creature tokens.
Activate Thermopod four times by sacrificing the four creature tokens, adding 4.
When the creature tokens die, Slimefoot triggers four times, dealing 4 damage to each opponent and causing you to gain 4 life.
Repeat
This delightful loop turns a simple fungus into an engine of attrition, anchored by Quina, Qu Gourmet's replacement effect turning every single Saproling creation into a bonus pair of token bodies. When you activate Slimefoot, the Stowaway, Illusionist's Bracers steps in to double the output, and feeding those resulting tokens to Thermopod generates the red mana needed to fund the next activation while fueling Slimefoot's triggered drain ability.
