Voltaic Construct

Circle of Dreams Druid

Silverskin Armor

How it works

1. Activate Circle of Dreams Druid by tapping it, adding at least .
2. Activate Voltaic Construct by paying 2, untapping Circle of Dreams Druid.
3. Repeat

This infinite mana loop turns a simple druid into an artifact-fueled powerhouse by utilizing Silverskin Armor to ensure Circle of Dreams Druid is recognized as an artifact creature. Once that equipment is attached, Voltaic Construct can step in to repeatedly untap the druid for a modest two-mana fee. As long as you control enough creatures to generate more than two green mana with each tap, Circle of Dreams Druid pays for the construct's ability and leaves a growing surplus behind, yielding infinite green mana and infinite untaps of your artifact creatures.
