Ioreth of the Healing House + Arixmethes, Slumbering Isle + Minamo, School at Water's Edge + Kamahl's Will
Ioreth of the Healing House
Arixmethes, Slumbering Isle
Minamo, School at Water's Edge
Kamahl's Will
Infinite green mana
How it works
Cast Kamahl's Will by paying 3, causing Arixmethes if it's a land and Minamo to become 1/1 Elementals with haste until end of turn.
Activate Arixmethes by tapping it, adding .
Activate Minamo's second ability by paying and tapping it, untapping Ioreth of the Healing House.
Activate Ioreth of the Healing House's second ability by tapping it, untapping Minamo and Arixmethes.
Repeat from step 2.
This clever loop transforms your lands into an engine of continuous mana production, anchored by Kamahl's Will to temporarily turn Arixmethes, Slumbering Isle and Minamo, School at Water's Edge into 1/1 Elemental creatures. Once they are creatures, Minamo's second ability can target the legendary Arixmethes to untap Ioreth of the Healing House, which in turn untaps both Minamo and Arixmethes with its second ability. This creates a closed circuit where tapping Arixmethes for {G}{U} easily pays the {U} activation cost while generating infinite green mana.
