Wirewood Lodge + Ley Weaver + Lotus Field + Runed Stalactite

Wirewood Lodge

Ley Weaver

Lotus Field

Runed Stalactite

How it works

1. Activate Lotus Field by tapping it, adding
2. Activate Ley Weaver by tapping it, untapping Wirewood Lodge and Lotus Field.
3. Activate Wirewood Lodge's second ability by paying and tapping it, untapping Ley Weaver.
4. Repeat.

This clever loop relies on Ley Weaver's ability to untap two lands, perfectly supercharged by Lotus Field's massive yield of three green mana. To complete the engine, Wirewood Lodge steps in to untap Ley Weaver for a single green mana, a feat made possible because Runed Stalactite conveniently bestows every creature type—including Elf—onto Ley Weaver so the Lodge can legally target her.
