Wirewood Lodge + Ley Weaver + Golgari Rot Farm + Amoeboid Changeling

Wirewood Lodge

Ley Weaver

Golgari Rot Farm

Amoeboid Changeling

How it works

1. Activate Amoeboid Changeling by tapping it, causing Ley Weaver to become an Elf until end of turn.
2. Activate Golgari Rot Farm by tapping it, adding
3. Activate Ley Weaver by tapping it, untapping Wirewood Lodge and Golgari Rot Farm.
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 a brilliant identity swap: Amoeboid Changeling uses its tap ability to turn Ley Weaver into an Elf, allowing it to benefit from external creature-type synergies. Once Ley Weaver is disguised as an Elf, tapping it to untap both Golgari Rot Farm and Wirewood Lodge generates a surplus of mana. You then use Wirewood Lodge's activated ability—fueled by the green mana you just produced—to untap Ley Weaver, resetting the loop. Meanwhile, Golgari Rot Farm serves as the power-generator that yields infinite black mana while letting you continually tap and untap your lands without ever running out of fuel.
