Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Etherium Sculptor + Ashnod's Altar

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Etherium Sculptor

Ashnod's Altar

How it works

1. Activate Ashnod's Altar 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 loop turns the recyclable nature of Cathodion into an engine of endless sacrifices and re-entries. Ashnod's Altar provides the initial colorless mana when you sacrifice Cathodion, whose own death trigger compensates by flooding your pool with even more energy. Meanwhile, Etherium Sculptor lightens the financial load, reducing the cost to replay your artifacts so that Edgar, Master Machinist can continually pull Cathodion right back out of the graveyard. Finally, Eldrazi Displacer keeps the board state fluid by resetting Edgar when needed, ensuring the whole operation runs in a seamless, self-sustaining circle.
