Shorikai, Genesis Engine + Voltaic Construct + Krark-Clan Ironworks + Biomancer's Familiar + Mycosynth Lattice

Shorikai, Genesis Engine

Voltaic Construct

Krark-Clan Ironworks

Biomancer's Familiar

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 engine turns every activation into a self-sustaining loop by weaving together a web of permanent transformations and cost reductions. Mycosynth Lattice makes all permanents into artifacts, meaning Shorikai, Genesis Engine and Voltaic Construct are both valid targets for the Construct's untap ability while remaining fully interactive with Krark-Clan Ironworks. With Biomancer's Familiar discounting Voltaic Construct's activation down to a single mana, you can tap Shorikai to draw cards and churn out a Pilot token, sacrifice that Pilot to the Ironworks for two generic mana, and use one of that mana to untap Shorikai with the Construct. The cycle repeats indefinitely, netting colorless mana and churning through your entire deck while triggering a storm of artifacts entering, leaving, and heading to the graveyard.
