Emry, Lurker of the Loch + Genesis Chamber + Phyrexian Altar + Copy Artifact

Emry, Lurker of the Loch

Genesis Chamber

Phyrexian Altar

Copy Artifact

How it works

1. Cast Emry by paying plus commander tax (if applicable).
2. When Emry enters the battlefield, it triggers itself, Genesis Chamber, and the copy of Genesis Chamber.
3. Resolve both Genesis Chamber triggers, creating two 1/1 Myr artifact creature tokens.
4. Resolve Emry's ability, milling four cards.
5. Activate Phyrexian Altar by sacrificing Emry, adding .
6. Send Emry from the graveyard to the command zone as a state-based action.
7. Repeat any number of times.
8. Once you have infinite creature tokens, you may activate Phyrexian Altar any number of times.

This ingenious loop relies on turning Emry, Lurker of the Loch into a self-sustaining engine by exploiting the parallel trigger of Genesis Chamber and a duplicate created via Copy Artifact. Each time Emry enters the battlefield, both Chambers reward you with two Myr tokens, which you can immediately feed into Phyrexian Altar along with Emry herself to generate the mana needed to recast her. Because Phyrexian Altar provides the exact blue mana required, and Emry's affinity for artifacts helps offset commander tax if needed, you can infinitely recast, sacrifice, and mill your way to an overwhelming board state.
