Wirewood Lodge + Ley Weaver + Jungle Basin + Runed Stalactite

Wirewood Lodge

Ley Weaver

Jungle Basin

Runed Stalactite

How it works

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

This intricate mana loop turns a humble bounce land into an infinite power plant by exploiting a clever loophole in creature types. With Runed Stalactite attached to Ley Weaver, she instantly becomes an Elf in addition to her other types, allowing her to be targeted by Wirewood Lodge's untap ability. Once the engine is rolling, Jungle Basin provides the initial green mana needed to pay Wirewood Lodge's activation cost while netting a surplus of colorless mana each cycle. This leaves Ley Weaver free to untap both the bounce land and the Lodge, repeating the entire process endlessly.
