Activate Shorikai by paying 1 and tapping it, causing you to draw two cards, discard a card, and create a 1/1 Pilot creature token.
Activate Krark-Clan Ironworks by sacrificing the Pilot, adding CC.
Activate Voltaic Construct by paying 1, untapping Shorikai.
Repeat.
By turning every nonland permanent you control into an artifact, Encroaching Mycosynth sets the stage for your entire board to interact in unprecedented ways, allowing Power Artifact to seamlessly discount the untap ability of Voltaic Construct down to just a single mana. With that cost reduction in place, Shorikai, Genesis Engine functions as an artifact creature that you can repeatedly tap to activate its card-drawing and Pilot-creating abilities. Whenever those Pilot tokens and other pieces need to be recycled, Krark-Clan Ironworks steps in to sacrifice them for the exact colorless mana needed to fuel the loop, letting you cycle through your deck indefinitely.
