Wirewood Lodge + Ley Weaver + Gruul Turf + Imagecrafter

Wirewood Lodge

Ley Weaver

Gruul Turf

Imagecrafter

How it works

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

This clever loop relies on Ley Weaver's ability to untap two lands at once, which we leverage on Gruul Turf to generate more mana than the cost to untap. Because Ley Weaver normally isn't an Elf, Imagecrafter steps in to bridge that gap by temporarily bestowing the Elf creature type, allowing Wirewood Lodge to untap Ley Weaver using its green mana ability. By looping this sequence, you can repeatedly tap and untap your lands to generate an infinite supply of red mana.
