Wirewood Lodge + Ley Weaver + Runed Stalactite + Nykthos, Shrine to Nyx

Wirewood Lodge

Ley Weaver

Runed Stalactite

Nykthos, Shrine to Nyx

How it works

1. Activate Nykthos by paying 2 and tapping it, adding an amount of equal to your devotion to it.
2. Activate Ley Weaver by tapping it, untapping Wirewood Lodge and Nykthos, Shrine to Nyx.
3. Activate Wirewood Lodge's second ability by paying and tapping it, untapping Ley Weaver.
4. Repeat.

This ingenious loop relies on turning Ley Weaver into an honorary Elf with Runed Stalactite so it can be repeatedly untap-cycled by Wirewood Lodge. Once the Weaver is properly typed, tapping it untaps Wirewood Lodge alongside Nykthos, Shrine to Nyx, which provides the massive green mana generation fueled by your devotion to green. You simply reinvest a portion of that green mana into Wirewood Lodge to untap Ley Weaver, restarting the cycle and rapidly generating infinite mana and untaps for your lands.
