Shorikai, Genesis Engine + Voltaic Construct + Krark-Clan Ironworks + Zirda, the Dawnwaker + Mycosynth Lattice

Shorikai, Genesis Engine

Voltaic Construct

Krark-Clan Ironworks

Zirda, the Dawnwaker

Mycosynth Lattice

How it works

1. Cause Shorikai to become a creature.
2. 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.
3. Activate Krark-Clan Ironworks by sacrificing the Pilot, adding CC.
4. Activate Voltaic Construct by paying 1, untapping Shorikai.
5. Repeat.

This intricate engine turns Shorikai, Genesis Engine into a self-sustaining draw and sacrifice machine by leveraging Mycosynth Lattice to treat all permanents as artifacts. With Mycosynth Lattice in play, Voltaic Construct can target Shorikai even when it's an artifact creature, while Zirda, the Dawnwaker steps in to discount Voltaic Construct's untap ability down to just a single mana. You activate Shorikai's tap ability to draw cards and churn out a Pilot token, which Krark-Clan Ironworks then happily sacrifices to generate the exact pair of colorless mana needed to fund the loop. The result is an endless cascade of draws, deaths, and artifact sacrifices that lets you dig through your entire deck at will.
