Voltaic Construct + Encroaching Mycosynth + Gyre Sage

Voltaic Construct

Encroaching Mycosynth

Gyre Sage

How it works

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

This clever loop turns any creature into a powerhouse of endless mana by reshaping the very nature of your board. With Encroaching Mycosynth turning every nonland permanent you control into an artifact in addition to its other types, Gyre Sage is no longer just a standard mana dork—it becomes an artifact creature eligible for mechanical tinkering. That classification is the linchpin that allows Voltaic Construct to target and untap Gyre Sage for a modest investment of two mana. As long as Gyre Sage holds enough +1/+1 counters to produce more than two green mana per tap, you can infinitely cycle those activations to generate boundless green mana and untaps for all your artifact creatures.
