Emry, Lurker of the Loch + Genesis Chamber + Phyrexian Altar + Mirrormade

Emry, Lurker of the Loch

Genesis Chamber

Phyrexian Altar

Mirrormade

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 clever loop relies on recasting Emry, Lurker of the Loch from the command zone while using Mirrormade to copy Genesis Chamber, doubling up the artifact token generation every time Emry enters the battlefield. As those new nontoken creatures trigger both Genesis Chamber and its Mirrormade double, you are flooded with Myr tokens that you can immediately feed into Phyrexian Altar to fund Emry's commander tax and recast her again. Because Emry's own entry triggers a self-mill, this sequence also digs deep into your library while churning out infinite mana, sacrifice triggers, and storm count.
