Voltaic Construct + Kydele, Chosen of Kruphix + Silverskin Armor

Voltaic Construct

Kydele, Chosen of Kruphix

Silverskin Armor

How it works

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

This delightful brewing puzzle turns Kydele, Chosen of Kruphix into a self-contained mana battery once you give her the mechanical heart of a machine. By outfitting her with Silverskin Armor, she becomes an artifact creature alongside her natural druid self, making her a legal target for Voltaic Construct. As long as you have drawn enough cards this turn to fuel the construct's activation cost, tapping Kydele for a flood of colorless mana allows you to immediately pay two of it to untap her with Voltaic Construct, creating a continuous loop of infinite colorless mana and infinite untaps.
