Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Krark-Clan Ironworks + Enthusiastic Mechanaut

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Krark-Clan Ironworks

Enthusiastic Mechanaut

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 intricate engine harnesses the sacrifice-happy machinery of Krark-Clan Ironworks to continuously feed Cathodion to the graveyard, where its death trigger generates a surplus of colorless mana. Enthusiastic Mechanaut lightens the financial load by discounting your artifact spells, allowing Edgar, Master Machinist to reliably pull Cathodion right back out of the graveyard and onto the battlefield for a cheap two mana. Meanwhile, Eldrazi Displacer stands ready to blink Edgar when needed, resetting the battlefield state so you can cycle your artifacts through the graveyard over and over again.
