Voltaic Construct + Memnarch + Gumato

Voltaic Construct

Memnarch

Gumato

How it works

1. Cause Gumato to become an artifact using Memnarch.
2. Activate Gumato by tapping it, adding
3. Activate Voltaic Construct by paying 2, untapping Gumato.
4. Repeat from step 2.

By using Memnarch to turn Gumato into an artifact, we lay the groundwork for a clever mechanical loop that lets Gumato tap for a massive burst of green mana. We then pump that mana right back into Voltaic Construct to untap Gumato, leaving us with a surplus of green energy each cycle. Because Memnarch’s transformation makes Gumato a valid target for Voltaic Construct's ability, these three pieces combine to generate infinite green mana and infinite untaps.
