Ashaya, Soul of the Wild + Stone-Seeder Hierophant + Dimir Aqueduct + PuPu UFO

Ashaya, Soul of the Wild

Stone-Seeder Hierophant

Dimir Aqueduct

PuPu UFO

How it works

1. Activate PuPu UFO by tapping it, putting Dimir Aqueduct from your hand onto the battlefield.
2. When Dimir Aqueduct enters, it and Stone-Seeder Hierophant trigger.
3. Resolve the Dimir Aqueduct 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 brilliant loop turns a mechanical quirk into an engine by letting PuPu UFO drop Dimir Aqueduct directly from your hand onto the battlefield. Thanks to Ashaya, Soul of the Wild, every creature you control functions as a Forest land alongside its other types, which cleverly transforms PuPu UFO into a legal target for Stone-Seeder Hierophant's untap ability. Whenever Dimir Aqueduct enters, its own trigger bounces it straight back to your hand while simultaneously triggering Stone-Seeder Hierophant's landfall ability, letting you endlessly repeat the process for infinite landfall triggers.
