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.
This intricate engine starts with Encroaching Mycosynth turning all your nonland permanents into artifacts, which allows Voltaic Construct to target Shorikai, Genesis Engine even when it is an artifact creature. With Zirda, the Dawnwaker reducing Voltaic Construct's untap ability to just {1}, you can repeatedly untap Shorikai after tapping it to activate its looting and Pilot-generating ability. Whenever a Pilot token is created, you simply feed it to Krark-Clan Ironworks to generate the mana needed to keep the loop going while churning through your entire deck.
