Lumra, Bellow of the Woods

Mirrorpool

Zuran Orb

Stone-Seeder Hierophant

How it works

1. Activate any number of other lands by tapping them, adding at least 4C.
2. Activate Zuran Orb by sacrificing a land except Mirrorpool.
3. Repeat step 2 until you control no lands except Mirrorpool.
4. Activate Mirrorpool's third ability by paying 4C, tapping and sacrificing it, creating a token copy of Lumra.
5. Put the Lumra token into your graveyard due to the legend rule.
6. The Lumra token's enters-the-battlefield ability triggers, causing you to mill four cards and return all land cards from your graveyard to the battlefield tapped.
7. When the lands enter the battlefield, Stone-Seeder Hierophant triggers that many times.
8. Resolve the first trigger, untapping Stone-Seeder Hierophant.
9. Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping a land.
10. Repeat from step 8 for the remaining triggers.
11. Repeat from step 1.
