Voltaic Construct + Liquimetal Torque + Wirewood Channeler

Voltaic Construct

Liquimetal Torque

Wirewood Channeler

How it works

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

By turning Wirewood Channeler into an artifact with Liquimetal Torque, we open the door to a clever machinery loop. With enough Elves on the field for Wirewood Channeler to produce at least three mana per tap, you can feed that energy straight into Voltaic Construct's activation cost to untap the Channeler and repeat the process. This self-sustaining cycle churns out infinite colored mana, ready to fund whatever grand design you have in mind.
