Wirewood Lodge + Ley Weaver + Amoeboid Changeling + Matzalantli, the Great Door // The Core

Wirewood Lodge

Ley Weaver

Amoeboid Changeling

Matzalantli, the Great Door // The Core

How it works

1. Activate Amoeboid Changeling by tapping it, causing Ley Weaver to become an Elf until end of turn.
2. Activate The Core by tapping it, adding at least .
3. Activate Ley Weaver by tapping it, untapping Wirewood Lodge and The Core.
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 boundless mana engine by cleverly manipulating creature types. Amoeboid Changeling uses its tap ability to turn Ley Weaver into an Elf, allowing Wirewood Lodge to untap it for a modest green investment. Meanwhile, Ley Weaver taps to untap both Wirewood Lodge and Matzalantli, the Great Door (transformed into The Core), which uses its fathomless descent ability to tap for massive quantities of colored mana fueled by your graveyard. By cycling these untap and mana-generation steps, you generate infinite colored mana and endlessly untap your lands.
