Voltaic Construct + Everflowing Chalice + Ensoul Artifact

Voltaic Construct

Everflowing Chalice

Ensoul Artifact

How it works

1. Activate Everflowing Chalice by tapping it, adding at least CCC
2. Activate Voltaic Construct by paying 2, untapping Everflowing Chalice.
3. Repeat.

To pull off this infinite mana loop, you first need to awaken **Everflowing Chalice** by casting it with enough multikicker so that tapping it produces at least three mana—more than enough to fuel the engine. **Ensoul Artifact** is the crucial catalyst that transforms that mundane chalice into a 5/5 artifact creature, making it a legal and eligible target for **Voltaic Construct**. Once the animated chalice is tapped for its bounty of mana, you pay two of that mana into the construct's ability to untap it, leaving you with a net gain of colorless energy every single iteration.
