Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Etherium Sculptor + Krark-Clan Ironworks

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Etherium Sculptor

Krark-Clan Ironworks

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 loop relies on the mana-generating machinery of Krark-Clan Ironworks and Cathodion to constantly fund the blinking and re-casting engine. By sacrificing Cathodion to the Ironworks, you trigger its death ability for a net gain of colorless mana, which allows Eldrazi Displacer to repeatedly exile and return Edgar, Master Machinist. Meanwhile, Etherium Sculptor lightens the financial load by reducing artifact costs, while Edgar's static ability lets you freely cast Cathodion straight back out of the graveyard after every cycle.
