Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Ashnod's Altar + Glaring Fleshraker

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Ashnod's Altar

Glaring Fleshraker

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 3.
5. Glaring Fleshraker's first ability triggers, creating a 0/1 Eldrazi Spawn creature token.
6. When the Eldrazi Spawn enters, Glaring Fleshraker's second ability triggers, dealing 1 damage to each opponent.
7. Resolve Cathodion. When it enters, Glaring Fleshraker's second ability triggers, dealing 1 damage to each opponent.
8. Activate Ashnod's Altar twice by sacrificing Cathodion and the Eldrazi Spawn, adding CCCC.
9. Repeat from step 2.

This intricate loop centers around Edgar, Master Machinist, whose static ability lets you continuously cast Cathodion straight from your graveyard while Ashnod's Altar converts that mechanical recycling into raw colorless mana. To fuel this engine, Eldrazi Displacer expertly blinks Edgar to clear any casting restrictions or reset the battlefield state, while Glaring Fleshraker turns every single iteration into a lethal cascade of damage by pinging opponents and generating an Eldrazi Spawn token for extra sacrifice fodder. Together, these five components weave a relentless loop that buries your foes under infinite triggers and endless colorless energy.
