Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Ashnod's Altar + Shuri, Wakandan Inventor

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Ashnod's Altar

Shuri, Wakandan Inventor

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 ingenious loop turns a modest pile of scrap into an infinite engine by leveraging Edgar, Master Machinist to recast artifacts directly from your graveyard. Ashnod's Altar provides the initial sacrifice outlet to feed the loop, while Cathodion plays the crucial role of a self-sacrificing battery, generating more mana on death than it costs to replay. Meanwhile, Eldrazi Displacer uses that generated colorless mana to repeatedly blink Edgar, refreshing your permission to cast from the graveyard and keeping the cycle spinning endlessly. While Shuri, Wakandan Inventor helps grease the wheels by reducing artifact costs to make the math easier, the combined engine ultimately yields infinite sacrifice, death, and entry triggers to overwhelm your opponents.
