Wirewood Lodge + Ley Weaver + Amoeboid Changeling + Evendo, Waking Haven

Wirewood Lodge

Ley Weaver

Amoeboid Changeling

Evendo, Waking Haven

How it works

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

This clever loop hinges on turning Ley Weaver into an Elf with Amoeboid Changeling's ability so that Wirewood Lodge can target and untap her after she taps to untap your lands. Once Ley Weaver resets along with Evendo, Waking Haven, you can leverage Evendo's massive mana-generation ability (or tap it for green mana) to continually fuel Wirewood Lodge's activation cost. Because Ley Weaver untaps two lands per cycle, you can keep the engine running indefinitely while generating infinite green mana and infinite untaps of the lands you control.
