This brilliant loop hinges on turning your lands into legendary creatures so they can participate in a closed, self-sustaining untap chain. Destiny Spinner does the vital setup work of making Minamo, School at Water's Edge an elemental creature, which safely elevates it to a legal target for both Minamo's own untap ability and Ioreth of the Healing House's second ability. Meanwhile, Arixmethes, Slumbering Isle naturally acts as a land while its slumber counters remain, letting it function as a mana source that produces {G}{U} when tapped. By using Ioreth of the Healing House and Minamo, School at Water's Edge to continually untap one another alongside Arixmethes, Slumbering Isle, you generate infinite green mana to fuel whatever devastating plays you need.
