Voltaic Construct + Memnarch + Deathbloom Ritualist

Voltaic Construct

Memnarch

Deathbloom Ritualist

How it works

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

This brilliant mechanical synthesis transforms Deathbloom Ritualist into an inexhaustible mana engine, provided your graveyard is sufficiently stocked to fuel its tap ability for at least three mana. The key to the loop is Memnarch, whose passive-capable transformation ability turns the Ritualist into an artifact, rendering it a valid target for Voltaic Construct's untap machinery. By funneling a portion of the mana generated by Deathbloom Ritualist back into the Construct's activation cost, you can endlessly untap your newly-minted artifact creature to net infinite colored mana. Memnarch can even leverage that newly acquired wealth to seize control of every permanent on the battlefield, turning your infinite mana into total domination.
