Myr Welder + Empowered Autogenerator + Gauntlets of Light

Myr Welder

Empowered Autogenerator

Gauntlets of Light

How it works

1. Activate Myr Welder using Empowered Autogenerator's ability by tapping it, putting a charge counter on it and adding for each charge counter on it
2. Activate Myr Welder by paying 2, untapping it.
3. Repeat.

By turning Myr Welder into a vessel through Empowered Autogenerator's exiled artifact ability, it gains the power to tap, accumulate charge counters, and flood your mana pool with ever-increasing amounts of colored mana. Gauntlets of Light provides the crucial missing piece, granting the enchanted Myr Welder an active untap ability that can be repeatedly funded by the very mana the Autogenerator produces. As the charge counters mount, the mana generated outpaces the cost of the untap loop, leaving you with an infinite supply of any color.
