Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Krark-Clan Ironworks

Duskwatch Recruiter // Krallenhorde Howler

How it works

1. Activate Krark-Clan Ironworks by sacrificing Cathodion, adding CC.
2. When Cathodion dies, it triggers, adding CCC.
3. Activate Eldrazi Displacer by paying 2C, blinking Edgar.
4. Cast Cathodion from your graveyard by paying 2.
5. Repeat.

This clever loop relies on Krark-Clan Ironworks to continuously sacrifice Cathodion, generating a surplus of colorless mana from both the sacrifice itself and Cathodion's own death trigger. Eldrazi Displacer uses that generated colorless mana to blink Edgar, Master Machinist, whose unique ability allows you to recast Cathodion straight from your graveyard on each of your turns. Meanwhile, Duskwatch Recruiter functions seamlessly in the background as Krallenhorde Howler, its passive cost-reduction ability helping to finance the recast cost of your looping artifacts.
