Eldrazi Displacer + Ashnod's Altar + Experimental Aviator

Eldrazi Displacer

Ashnod's Altar

Experimental Aviator

How it works

1. Activate Eldrazi Displacer by paying 2C, blinking Experimental Aviator.
2. When Experimental Aviator enters, it triggers, creating two creature tokens.
3. Activate Ashnod's Altar by sacrificing two creature tokens, adding CCCC.
4. Repeat.

This charming loop turns Experimental Aviator into a self-sustaining engine by utilizing the entering creature's pair of Thopter tokens to fund the process. By feeding those newly minted tokens into Ashnod's Altar, you generate more than enough colorless mana to cover the activation cost of Eldrazi Displacer, which promptly resets the Aviator to repeat the whole cycle. Because the Altar yields four mana for every two sacrifices while the Displacer only demands three to blink, you are left with a steadily growing surplus of colorless mana alongside an endless swarm of flying metal.
