Voltaic Construct + Katsumasa, the Animator + White Lotus Tile

Voltaic Construct

Katsumasa, the Animator

White Lotus Tile

How it works

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

This clever loop relies on Katsumasa, the Animator to turn White Lotus Tile into an artifact creature during your turn, bypassing its usual inability to tap for mana the moment it enters the battlefield. Once animated and tapped for at least three mana—thanks to its ability scaling with your creature types—you can funnel just two of that mana into Voltaic Construct to instantly untap it. Because Voltaic Construct's untap ability targets any artifact creature, this creates a closed loop that generates infinite colored mana and an arbitrarily large supply of untaps for your entire mechanical army.
