Voltaic Construct + The Flesh Is Weak + Gumato

Voltaic Construct

The Flesh Is Weak

Gumato

How it works

1. Activate Gumato by tapping it, adding
2. Activate Voltaic Construct by paying 2, untapping Gumato.
3. Repeat

This clever loop turns your entire creature base into a self-sustaining mana engine. It all begins with The Flesh Is Weak, whose static ability gives all your creatures +1/+1 counters and transforms them into artifacts in addition to their other types. Because Gumato is now an artifact creature, it can be targeted by Voltaic Construct's untap ability. By tapping Gumato for three green mana and using two of it to untap it with Voltaic Construct, you generate an infinite loop of green mana and untaps.
