This clever brew transforms the humble Horseshoe Crab into a self-sustaining engine by equipping it with Illusionist's Bracers and enchanting it with Karametra's Favor. When you activate the Crab's untap ability, the Bracers spring into action to duplicate it, ensuring you always have an extra untap resolution left over to chain endlessly. Meanwhile, the mana-producing gift bestowed by Karametra's Favor lets you tap the Crab for any color of mana in the middle of these loops, safely funding the blue mana required to keep the Crab's own ability running forever.
