Voltaic Construct + Katsumasa, the Animator + The Eternity Elevator

Voltaic Construct

Katsumasa, the Animator

The Eternity Elevator

How it works

1. Animate The Eternity Elevator using Katsumasa.
2. Activate The Eternity Elevator by tapping it, adding CCC.
3. Activate Voltaic Construct by paying 2, untapping The Eternity Elevator.
4. Repeat from step 2.

This clever engine turns The Eternity Elevator into a self-sustaining mana core by using Katsumasa, the Animator to give it the necessary artifact creature status. Once animated, tapping The Eternity Elevator yields three colorless mana, which readily funds the {2} activation cost of Voltaic Construct to untap it right back. Repeating this loop endlessly generates infinite colorless mana, while Katsumasa, the Animator's presence ensures your key piece remains an active creature capable of being continuously untaped.
