Nim Deathmantle + Krark-Clan Ironworks + Essence of Orthodoxy

Nim Deathmantle

Krark-Clan Ironworks

Essence of Orthodoxy

How it works

1. Activate Krark-Clan Ironworks by sacrificing a nontoken artifact Phyrexian creature you control, adding CC.
2. When the Phyrexian dies, Nim Deathmantle triggers, causing you to pay 4 to return the Phyrexian from your graveyard to the battlefield, and attach Nim Deathmantle to it.
3. When the Phyrexian enters the battlefield, Essence of Orthodoxy triggers, creating an Incubator artifact token.
4. Activate Krark-Clan Ironworks by sacrificing the Incubator, adding CC.
5. Repeat.
