Derevi, Empyrial Tactician + The Golden Throne + Genesis Chamber + Phyrexian Altar

Derevi, Empyrial Tactician

The Golden Throne

Genesis Chamber

Phyrexian Altar

How it works

1. Activate The Golden Throne by tapping it and sacrificing Derevi, adding .
2. Choose to return Derevi to the command zone from your graveyard.
3. Activate Derevi by paying 1, putting Derevi onto the battlefield from the command zone.
4. When Derevi enters the battlefield, it and Genesis Chamber trigger.
5. Resolve the Genesis Chamber trigger, creating a 1/1 Myr artifact creature token.
6. Resolve the Derevi trigger, untapping The Golden Throne.
7. Activate Phyrexian Altar by sacrificing the Myr, adding 1.
8. Repeat.

This clever loop sets up an infinite engine centered around the commander zone by using Derevi, Empyrial Tactician to repeatedly untap The Golden Throne. Each iteration is fueled by sacrificing Derevi to The Golden Throne for mana and returning Derevi to the command zone, then recasting Derevi for its alternate command cost while Phyrexian Altar and Genesis Chamber work together to continuously generate and sacrifice Myr artifact creature tokens for the extra mana needed to sustain the cycle.
