Stone-Seeder Hierophant + Drownyard Temple + Nykthos, Shrine to Nyx + Zuran Orb

Stone-Seeder Hierophant

Drownyard Temple

Nykthos, Shrine to Nyx

Zuran Orb

How it works

1. Activate Nykthos' second ability by paying 2 and tapping it, adding at least 5.
2. Activate Stone-Seeder Hierophant by tapping it, untapping Nykthos.
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.
7. If you have at least six devotion to any color, this combo nets infinite mana.

This brilliant loop relies on Nykthos, Shrine to Nyx generating an excess of colored mana, which is then filtered to fuel the rest of the machinery. With your devotion providing enough surplus, you tap Stone-Seeder Hierophant to ready Nykthos once more, while Zuran Orb provides an instant sacrifice outlet to feed the land back into the graveyard. From there, Drownyard Temple's ability brings itself right back to the battlefield, turning that graveyard recursion into a fresh landfall trigger that untaps Stone-Seeder Hierophant to do it all over again.
