Edgar, Master Machinist + Eldrazi Displacer + Cathodion + Ashnod's Altar + Voyager Quickwelder

Edgar, Master Machinist

Eldrazi Displacer

Cathodion

Ashnod's Altar

Voyager Quickwelder

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 Cathodion and Ashnod's Altar into a self-sustaining mana engine, where sacrificing the automaton yields five total colorless mana to comfortably fund your activations. To keep the gears turning, Eldrazi Displacer uses that mana to repeatedly blink Edgar, Master Machinist, whose static ability lets you cast Cathodion straight back from the graveyard each time. Meanwhile, Voyager Quickwelder quietly greases the machinery by discounting that artifact casting cost to just two mana, ensuring you generate a surplus of colorless energy with every single iteration.
