Ioreth of the Healing House + Arixmethes, Slumbering Isle + Minamo, School at Water's Edge + Nissa, Worldwaker

Ioreth of the Healing House

Arixmethes, Slumbering Isle

Minamo, School at Water's Edge

Nissa, Worldwaker

How it works

1. Activate Nissa's first loyalty ability by putting a loyalty counter on it, causing Minamo to become a 4/4 Elemental creature that's still a land.
2. Activate Arixmethes by tapping it, adding .
3. Activate Minamo's second ability by paying and tapping it, untapping Ioreth of the Healing House.
4. Activate Ioreth of the Healing House's second ability by tapping it, untapping Minamo and Arixmethes.
5. Repeat from step 2.

This brilliant loop relies on turning your lands into legendary creatures so they can feed Ioreth of the Healing House and Minamo, School at Water's Edge in a closed circuit of untapped resources. Nissa, Worldwaker provides the crucial static-turned-active catalyst by animating Minamo, School at Water's Edge into a 4/4 Elemental creature—making it a legendary permanent that can both tap for mana and be targeted by Minamo's own untap ability. With Arixmethes, Slumbering Isle naturally acting as a massive mana source that can also be targeted by Ioreth's dual-untap ability, you have all the pieces needed to continuously generate a surplus of green mana.
