Wirewood Lodge + Ley Weaver + Amoeboid Changeling + Selesnya Sanctuary

Wirewood Lodge

Ley Weaver

Amoeboid Changeling

Selesnya Sanctuary

How it works

1. Activate Amoeboid Changeling by tapping it, causing Ley Weaver to become an Elf until end of turn.
2. Activate Selesnya Sanctuary by tapping it, adding
3. Activate Ley Weaver by tapping it, untapping Wirewood Lodge and Selesnya Sanctuary.
4. Activate Wirewood Lodge's second ability by paying and tapping it, untapping Ley Weaver.
5. Repeat from step 2.

This clever loop turns an unlikely trio into a self-sustaining mana engine, built around Ley Weaver's ability to untap two lands at once. Since Ley Weaver needs to be an Elf to be untapable by Wirewood Lodge, Amoeboid Changeling steps in with its type-granting ability to bridge that gap. With Selesnya Sanctuary providing the vital green mana needed to fuel Wirewood Lodge's untap activation, you can continually untap both lands and repeat the cycle to generate an unbounded supply of white mana.
