Voltaic Construct + Wirewood Channeler + The Flesh Is Weak

Voltaic Construct

Wirewood Channeler

The Flesh Is Weak

How it works

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

This elegant loop relies on turning your mana dork into an artifact so it can repeatedly ready itself. With The Flesh Is Weak on the battlefield, its static ability grants +1/+1 counters to your creatures as it enters—which in turn transforms Wirewood Channeler and your other creatures into artifacts alongside their creature types. Once Wirewood Channeler is an artifact creature, tapping it to generate mana makes it the ideal target for Voltaic Construct's ability, allowing you to filter a portion of that mana back to untap the Channeler and repeat the process indefinitely for infinite colored mana.
