Voltaic Construct + Circle of Dreams Druid + Neurok Transmuter

Voltaic Construct

Circle of Dreams Druid

Neurok Transmuter

How it works

1. Cause Circle of Dreams Druid to become an artifact using Neurok Transmuter.
2. Activate Circle of Dreams Druid by tapping it, adding at least .
3. Activate Voltaic Construct by paying 2, untapping Circle of Dreams Druid.
4. Repeat from step 2.

This clever three-card assembly turns your creature-heavy board into a bottomless green reservoir by fundamentally rewriting what your permanents are made of. First, Neurok Transmuter applies its crucial passive-turned-active manipulation to make Circle of Dreams Druid an artifact, opening the door for Voltaic Construct to target it. Once that transformation is locked in for the turn, tapping Circle of Dreams Druid yields a massive influx of green mana scaled directly to your creature count. You then channel a portion of that bounty back into Voltaic Construct to untap the Druid, clearing the way to repeat the loop indefinitely for infinite green mana and infinite untaps.
