Voltaic Construct + Circle of Dreams Druid + Memnarch

Voltaic Construct

Circle of Dreams Druid

Memnarch

How it works

1. Cause Circle of Dreams Druid to become an artifact using Memnarch.
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 delightful loop hinges on turning your mana-producing druid into a piece of clockwork machinery so it can be endlessly reset. By using Memnarch's first ability to turn Circle of Dreams Druid into an artifact, it becomes a legal target for Voltaic Construct's untap ability. Once the druid is tapping to generate massive amounts of green mana thanks to Circle of Dreams Druid's creature-counting mana ability, you simply feed a small slice of that profit back into Voltaic Construct to stand the druid back up. Memnarch provides the crucial type-changing glue that makes the whole engine work, letting you generate infinite green mana and infinite untaps of your artifact creatures in Commander, Legacy, Modern, Oathbreaker, and Vintage.
