Voltaic Construct + Liquimetal Torque + Karametra's Acolyte

Voltaic Construct

Liquimetal Torque

Karametra's Acolyte

How it works

1. Cause Karametra's Acolyte to become an artifact using Liquimetal Torque.
2. Activate Karametra's Acolyte by tapping it, adding at least .
3. Activate Voltaic Construct by paying 2, untapping Karametra's Acolyte.
4. Repeat from step 2.

This elegant loop transforms a humble mana dork into an engine of boundless green energy by weaponizing its type-changing properties. With Liquimetal Torque turning Karametra's Acolyte into an artifact, the creature becomes a legal target for Voltaic Construct's untap ability. As long as your devotion to green yields at least three mana from Karametra's Acolyte, paying the two-mana activation cost to untap it with Voltaic Construct leaves you with a net profit of green mana every single cycle.
