Wirewood Lodge + Ley Weaver + Amoeboid Changeling + Nykthos, Shrine to Nyx

Wirewood Lodge

Ley Weaver

Amoeboid Changeling

Nykthos, Shrine to Nyx

How it works

1. Activate Amoeboid Changeling by tapping it, causing Ley Weaver to become an Elf until end of turn.
2. Activate Nykthos by paying 2 and tapping it, adding an amount of equal to your devotion to green.
3. Activate Ley Weaver by tapping it, untapping Wirewood Lodge and Nykthos, Shrine to Nyx.
4. Activate Wirewood Lodge's second ability by paying and tapping it, untapping Ley Weaver.
5. Repeat from step 2.

This clever loop turns your battlefield into a self-sustaining mana engine by taking advantage of creature type manipulation. While Nykthos, Shrine to Nyx provides the explosive green mana fueled by your devotion, Ley Weaver acts as the tireless workhorse whose tap ability untaps both Nykthos and Wirewood Lodge. Because Ley Weaver needs to be untappable by Wirewood Lodge's green-mana-activated ability, Amoeboid Changeling steps in with its changeling identity and targeted effect to temporarily grant Ley Weaver the Elf creature type. With Wirewood Lodge untapping the Weaver and the Weaver in turn resetting your lands, you generate infinite untaps and infinite green mana.
