Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Helm of Awakening + Ashnod's Altar

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Helm of Awakening

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 loop is a masterclass in resource recycling, fueled entirely by the constant sacrifice and rebirth of Cathodion. When you feed Cathodion to Ashnod's Altar, its own death trigger combines with the Altar's sacrifice payout to net you a surplus of colorless mana. Meanwhile, Eldrazi Displacer uses that mana to blink Edgar, Master Machinist, whose static ability lets you effortlessly recast Cathodion straight from your graveyard. To keep the math flowing smoothly, Helm of Awakening discounts that casting cost down to just two mana, ensuring you generate a permanent profit of colorless mana on every single iteration.
