Wirewood Lodge + Ley Weaver + Golgari Rot Farm + Oko, Lorwyn Liege // Oko, Shadowmoor Scion

Wirewood Lodge

Ley Weaver

Golgari Rot Farm

Oko, Lorwyn Liege // Oko, Shadowmoor Scion

How it works

1. Activate Oko's first loyalty ability by putting two loyalty counters on it, causing Ley Weaver to gain all creature types.
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 infinite mana engine relies on turning Ley Weaver into an Elf with Oko, Lorwyn Liege // Oko, Shadowmoor Scion's first loyalty ability so it can be untap-targeted by Wirewood Lodge. Once Ley Weaver is an Elf, tapping it to untap Wirewood Lodge and a mana-producing land—specifically Golgari Rot Farm—creates a self-sustaining loop where Wirewood Lodge's green mana cost is continually paid to untap Ley Weaver right back. Because Golgari Rot Farm taps for both black and green mana, every iteration of this untap cycle generates a surplus of black mana, fueling your spells indefinitely.
