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 Shorikai, Genesis Engine into an artifact creature with the help of Biotransference, we unlock a remarkably efficient self-sustaining loop. Zirda, the Dawnwaker is the linchpin that makes the math work, reducing the activation cost of Voltaic Construct to just {1} mana. We tap Shorikai to draw cards and churn out a Pilot token, sacrifice that Pilot to Krark-Clan Ironworks for two colorlessly produced mana, and use one of those mana to have Voltaic Construct untap Shorikai—leaving us with a net profit of mana and an endless churn of draws and sacrifices.
