Eldrazi Displacer + Eyeless Watcher + Primal Vigor

Eldrazi Displacer

Eyeless Watcher

Primal Vigor

How it works

1. Activate Eldrazi Displacer by paying 2C, blinking Eyeless Watcher.
2. When Eyeless Watcher enters the battlefield, it triggers, creating four 1/1 Eldrazi Scion creature tokens.
3. Activate three Eldrazi Scions by sacrificing them, adding CCC.
4. Repeat.

This clever loop lets you turn a single investment of colorless mana into an expanding horde of Eldrazi Scions and endless triggers, perfectly suited for formats like Commander and Legacy. The engine hums when you use Eldrazi Displacer's activated ability to blink Eyeless Watcher, resetting its enter-the-battlefield trigger. Thanks to Primal Vigor doubling every token that appears, Eyeless Watcher yields four Eldrazi Scions instead of two, creating more than enough sacrifice fodder to generate the colorless mana needed to keep Eldrazi Displacer firing over and over again.
