Tezzeret's Anomaly

Cataclast - At the beginning of each of your end steps, you may sacrifice a nonartifact permanent that shares a color with Tezzeret's Anomaly. If
you do, create a colorless artifact token named Etherium Cell with "{t}, Sacrifice this artifact:
Add one mana of any color."
"It was a lack of diligence on his father's part that allowed Tezzeret to begin stealing etherium. This etherium belonged to me. I want it back."
- Catal, the First Anomaly
