Ashaya, Soul of the Wild + Stone-Seeder Hierophant + Scaled Herbalist + Dimir Aqueduct

Ashaya, Soul of the Wild

Stone-Seeder Hierophant

Scaled Herbalist

Dimir Aqueduct

How it works

1. Activate Scaled Herbalist 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 Scaled Herbalist as it is a land due to Ashaya.
6. Repeat.

This elegant loop transforms the humble act of playing a land into a perpetual motion machine by turning your creatures into forests with Ashaya, Soul of the Wild. Because Ashaya makes Stone-Seeder Hierophant a land, the Hierophant can untap itself and Scaled Herbalist whenever a land enters, creating a self-sustaining cycle where Scaled Herbalist repeatedly drops Dimir Aqueduct from your hand. Dimir Aqueduct's own bounce trigger ensures you never run out of cards to play, while the Hierophant's tap ability keeps the engine fully fueled.
