Cayth, Famed Mechanist + Nim Deathmantle + Krark-Clan Ironworks

Cayth, Famed Mechanist

Nim Deathmantle

Krark-Clan Ironworks

How it works

1. Activate Krark-Clan Ironworks by sacrificing a nontoken artifact creature, adding CC.
2. When the creature dies, Nim Deathmantle triggers, causing you to pay 4 to return the creature from your graveyard to the battlefield, and attach Nim Deathmantle to it.
3. When the creature enters the battlefield, its fabricate ability triggers, creating a 1/1 Servo artifact creature token.
4. Activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
5. Repeat.

This clever loop hinges on turning your artifacts and creatures into a self-sustaining engine of creation and sacrifice. By using Krark-Clan Ironworks to sacrifice a nontoken creature, you generate the mana needed to fuel Nim Deathmantle's revival trigger when that creature hits the graveyard. When the creature returns, the static presence of Cayth, Famed Mechanist grants it fabricate 1, immediately generating a Servo token that you can feed right back into Krark-Clan Ironworks for more mana.
