Voltaic Construct + Astral Cornucopia + Katsumasa, the Animator

Voltaic Construct

Astral Cornucopia

Katsumasa, the Animator

How it works

1. Animate Astral Cornucopia using Katsumasa.
2. Activate Astral Cornucopia by tapping it, adding at least three mana of any color
3. Activate Voltaic Construct by paying 2, untapping Astral Cornucopia.
4. Repeat from step 2.

This clever loop transforms a humble artifact into a mana-producing powerhouse by letting Katsumasa, the Animator temporarily turn Astral Cornucopia into an artifact creature with flying. Once animated, Astral Cornucopia can tap for three or more mana (assuming it has entered with enough charge counters), which effortlessly funds the activation cost of Voltaic Construct. As Voltaic Construct untaps the Cornucopia, you clear the way to repeat the process endlessly, generating infinite colored mana to fuel the rest of your strategy.
