Ioreth of the Healing House + Arixmethes, Slumbering Isle + Minamo, School at Water's Edge + Wrenn and Realmbreaker
Ioreth of the Healing House
Arixmethes, Slumbering Isle
Minamo, School at Water's Edge
Wrenn and Realmbreaker
Infinite green mana
How it works
Activate Wrenn and Realmbreaker's first loyalty ability by putting a loyalty counter on it, causing Minamo to become a 3/3 Elemental creature with vigilance, hexproof and haste that's still a land until your next 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 fascinating loop turns our legendary land into a self-sustaining mana engine, starting with Wrenn and Realmbreaker animating Minamo, School at Water's Edge so it can count as a legendary creature. Once awakened, Minamo spends some of its blue mana to untap Ioreth of the Healing House, which in turn untaps both Minamo and Arixmethes, Slumbering Isle simultaneously using its ability targeting two legendary creatures. Because Arixmethes, Slumbering Isle naturally taps for two mana and Wrenn and Realmbreaker's passive ability grants every land the power to tap for any color, the green mana generated easily outpaces the blue mana required for Minamo's activation.
