Ashaya, Soul of the Wild + Stone-Seeder Hierophant + Scaled Herbalist + Izzet Boilerworks

Ashaya, Soul of the Wild

Stone-Seeder Hierophant

Scaled Herbalist

Izzet Boilerworks

How it works

1. Activate Scaled Herbalist by tapping it, putting Izzet Boilerworks from your hand onto the battlefield.
2. When Izzet Boilerworks enters, it and Stone-Seeder Hierophant trigger.
3. Resolve the Izzet Boilerworks 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 brilliant loop turns your entire creature base into a self-sustaining mana-and-landfall engine, anchored by Ashaya, Soul of the Wild making every nontoken creature you control a Forest land. That land type transformation is the secret glue, allowing Stone-Seeder Hierophant to target and untap Scaled Herbalist whenever a land enters or via its own tap ability. With Scaled Herbalist constantly dropping Izzet Boilerworks back onto the battlefield from your hand—which continuously bounces itself right back to your hand—Stone-Seeder Hierophant triggers off each new arrival to reset the loop indefinitely.
