Emry, Lurker of the Loch + Genesis Chamber + Phyrexian Altar + Clever Impersonator

Emry, Lurker of the Loch

Genesis Chamber

Phyrexian Altar

Clever Impersonator

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 sets up an endless cycle of artifact creation and sacrifice by using Clever Impersonator to duplicate Genesis Chamber, doubling up on the Myr tokens generated whenever a creature enters. With Phyrexian Altar providing a sacrifice outlet that immediately refunds the mana needed to recast your commander, Emry, Lurker of the Loch can continuously re-enter from the graveyard or command zone. Each iteration fuels both the Altar and the Chambers, letting you churn out infinite mana, tokens, and death triggers while chewing through your library.
