This clever loop turns your own lands into a self-sustaining mana engine, starting when you use Unnatural Selection to temporarily turn Ley Weaver into an Elf. That type change is crucial because it allows Ley Weaver to be targeted by Wirewood Lodge's untap ability, bridging the gap between your land base and your creatures. Once Ley Weaver is set up, tapping Lotus Field generates a massive influx of mana, which you use to fund the back-and-forth untapping between Ley Weaver and Wirewood Lodge.
