Voltaic Construct + Liquimetal Torque + Rofellos, Llanowar Emissary

Voltaic Construct

Liquimetal Torque

Rofellos, Llanowar Emissary

How it works

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

By turning Rofellos, Llanowar Emissary into an artifact via Liquimetal Torque, we set the stage for our metallic mana producer to be targeted by Voltaic Construct's untap ability. Because Rofellos taps to generate an explosive amount of green mana—thanks to the Forests you control—you will easily have enough to pay the Construct's activation cost and still profit handsomely. This loop allows you to continually untap your newly-minted artifact creature, netting infinite green mana in the process.
