Voltaic Construct + Overgrown Battlement + Encroaching Mycosynth

Voltaic Construct

Overgrown Battlement

Encroaching Mycosynth

How it works

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

This clever loop relies entirely on Encroaching Mycosynth to transform your entire nonland board—most importantly, your defenders—into artifacts, which seamlessly bridges our mana producer and our untapper. Once that foundation is set, you tap Overgrown Battlement for a massive influx of green mana, fueled by the number of defenders you control. You then funnel a portion of that energy directly into Voltaic Construct to untap the Battlement, leaving you with a surplus of green mana to repeat the process infinitely.
