Voltaic Construct + Chromatic Orrery + Katsumasa, the Animator

Voltaic Construct

Chromatic Orrery

Katsumasa, the Animator

How it works

1. Animate Chromatic Orrery using Katsumasa.
2. Activate Chromatic Orrery by tapping it, adding CCCCC
3. Activate Voltaic Construct by paying 2, untapping Chromatic Orrery.
4. Repeat from step 2.

This clever loop transforms a massive mana engine into an endless fountain of resources. By using Katsumasa, the Animator to turn Chromatic Orrery into an artifact creature, it becomes a valid target for Voltaic Construct's untap ability. Tapping the Orrery generates five colorless mana—more than enough to pay the Construct's two-mana activation fee—while Chromatic Orrery's static ability lets you freely filter that colorless surplus into any color you desire. Once you have an infinite loop of mana and untaps established, you can repeatedly tap and untap the Orrery to draw your entire deck and win the game.
