Ashaya, Soul of the Wild + Stone-Seeder Hierophant + Llanowar Scout + Arid Archway

Ashaya, Soul of the Wild

Stone-Seeder Hierophant

Llanowar Scout

Arid Archway

How it works

1. Activate Llanowar Scout by tapping it, putting Arid Archway from your hand onto the battlefield.
2. When Arid Archway enters, it and Stone-Seeder Hierophant trigger.
3. Resolve the Arid Archway 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 Llanowar Scout as it is a land due to Ashaya.
6. Repeat.

This loop transforms the battlefield into a self-sustaining engine by turning all your creatures into lands through Ashaya, Soul of the Wild's continuous effect. Because Ashaya makes Llanowar Scout a land, Stone-Seeder Hierophant can tap to untap it, allowing the Scout to repeatedly drop Arid Archway from your hand. Every time Arid Archway enters, its landfall ability and Stone-Seeder Hierophant's landfall trigger both fire off, with the Hierophant untapping itself so you can keep the cycle going. Since Arid Archway bounces itself right back to your hand as it enters, you have an endless supply of land drops to fuel infinite landfall triggers.
