Emry, Lurker of the Loch + Aura of Dominion + Ashnod's Altar + Phyrexian Walker

Emry, Lurker of the Loch

Aura of Dominion

Ashnod's Altar

Phyrexian Walker

How it works

1. Activate Ashnod's Altar by sacrificing the Phyrexian Walker, adding CC.
2. Activate Emry by tapping it, allowing you to cast Phyrexian Walker from your graveyard this turn.
3. Cast Phyrexian Walker from your graveyard by paying 0
4. Activate Aura of Dominion by paying 1 and tapping Phyrexian Walker, untapping Emry.
5. Repeat.

This clever loop revolves around Emry, Lurker of the Loch utilizing her tap ability to continually pull artifacts from the graveyard, supercharged by Aura of Dominion keeping her perpetually untapping. To fuel that untap cost, we sacrifice the free-to-cast Phyrexian Walker to Ashnod's Altar, which not only generates the necessary mana to sustain the Aura but also banks a profit of colorless mana along the way. Because Phyrexian Walker requires zero mana to recast via Emry's graveyard-casting effect, the entire engine runs in a self-sustaining cycle that yields infinite death triggers and colorless mana.
