This looping engine starts the moment you gain any initial life to kick off Trudge Garden, allowing you to pay into a steady stream of 4/4 Fungus Beast tokens. As each beast enters, Bogwater Lumaret provides a crucial cushion of lifegain to keep the garden fed, while Pitiless Plunderer quietly watches the graveyard to manufacture a Treasure token every time a creature perishes. Meanwhile, Thermopod acts as the sacrificial altar at the heart of the operation, converting your temporary beasts into the red mana needed alongside the Treasure's payload to continually pay Trudge Garden's fee.
