Voltaic Construct + Ygra, Eater of All + Topiary Lecturer

Voltaic Construct

Ygra, Eater of All

Topiary Lecturer

How it works

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

This infinite green mana engine relies on a clever transformation of the battlefield courtesy of Ygra, Eater of All, which turns all other creatures into Food artifacts in addition to their other types. Because Topiary Lecturer is now an artifact creature, it becomes a valid target for Voltaic Construct's ability, allowing you to pay {2} to untap the mana dork repeatedly. With Topiary Lecturer's power pumped high enough by Ygra's second ability—which triggers and grows Ygra whenever these Foods hit the graveyard—tapping it produces far more than the {2} needed for Voltaic Construct, netting you limitless green mana.
