This delightful loop turns ordinary green-mana acceleration into an infinite mana engine by overlaying Weirding Wood onto a Forest, transforming it into a powerhouse that taps for two mana of any color. Arbor Elf does the heavy lifting by tapping and untapping that enchanted land, but to make the process self-sustaining, Pemmin's Aura steps in to untap the Elf using a single unit of the blue mana generated by the land. Because the Weirding Wood land produces two mana per tap while Pemmin's Aura only requires one blue mana to untap Arbor Elf, you net one extra mana with every single iteration—allowing you to easily swap to generating infinite quantities of any color you desire.
