Ashaya, Soul of the Wild + Stone-Seeder Hierophant + Golgari Rot Farm + PuPu UFO

Ashaya, Soul of the Wild

Stone-Seeder Hierophant

Golgari Rot Farm

PuPu UFO

How it works

1. Activate PuPu UFO by tapping it, putting Golgari Rot Farm from your hand onto the battlefield.
2. When Golgari Rot Farm enters, it and Stone-Seeder Hierophant trigger.
3. Resolve the Golgari Rot Farm trigger, returning it from the battlefield to your hand.
4. Resolve the Stone-Seeder Hierophant trigger, untapping it.
5. Activate Stone-Seeder Hierophant by tapping it, untapping PuPu UFO as it is a land due to Ashaya.
6. Repeat.

This intricate loop leverages Ashaya, Soul of the Wild to fundamentally rewrite the rules of your board, transforming every creature you control into a Forest land in addition to its other types. That crucial static ability turns Stone-Seeder Hierophant and PuPu UFO into legal targets for land-based untapping and lets Stone-Seeder Hierophant untap PuPu UFO directly. By using PuPu UFO to repeatedly drop Golgari Rot Farm—which bounces itself upon entry to fuel the next cycle—you continuously trigger Stone-Seeder Hierophant's landfall ability to sustain the loop.
