Stone-Seeder Hierophant + Drownyard Temple + Scorched Ruins + Zuran Orb

Stone-Seeder Hierophant

Drownyard Temple

Scorched Ruins

Zuran Orb

How it works

1. Activate Scorched Ruins by tapping it, adding CCCC.
2. Activate Stone-Seeder Hierophant by tapping it, untapping Scorched Ruins.
3. Activate Drownyard Temple by paying 3, returning it from your graveyard to the battlefield tapped.
4. When Drownyard Temple enters the battlefield, Stone-Seeder Hierophant triggers, untapping Stone-Seeder Hierophant.
5. Activate Zuran Orb by sacrificing Drownyard Temple, causing you to gain 2 life.
6. Repeat.

This clever engine harnesses the immense mana-producing power of Scorched Ruins, which taps for four colorless mana, to fund a self-sustaining loop. By using Zuran Orb to sacrifice Drownyard Temple—which is then brought right back to the battlefield using some of that generated mana—you trigger Stone-Seeder Hierophant's landfall ability, keeping your untap actions flowing smoothly. That very same Stone-Seeder Hierophant can also be tapped directly to untap your lands, ultimately generating infinite colorless mana, infinite life, and boundless landfall triggers.
