Patron of the Moon + Cloudstone Curio + Stone-Seeder Hierophant

Patron of the Moon

Cloudstone Curio

Stone-Seeder Hierophant

How it works

1. Activate Patron of the Moon by paying 1, putting two nonartifact lands from your hand onto the battlefield tapped.
2. When the lands enter, Stone-Seeder Hierophant and Cloudstone Curio trigger twice.
3. Resolve a Stone-Seeder Hierophant trigger, untapping it.
4. Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping a mana-producing land.
5. Activate the land by tapping it, adding at least 1.
6. Repeat from step 3 for the other Stone-Seeder Hierophant trigger.
7. Resolve both Cloudstone Curio triggers, returning the lands from the battlefield to your hand.
8. Repeat.
