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

Shorikai, Genesis Engine

Voltaic Construct

Krark-Clan Ironworks

Biomancer's Familiar

Encroaching Mycosynth

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 an infinite card-drawing machine by leveraging a clever web of permanents to bypass its usual activation limits. Encroaching Mycosynth is the linchpin that transforms your entire board—making Voltaic Construct and Biomancer's Familiar into artifacts alongside Shorikai—so that everything synergizes seamlessly. Biomancer's Familiar reduces Voltaic Construct's untap cost to a single mana, which allows you to continually untap Shorikai after tapping it to draw cards and create a Pilot token. Finally, Krark-Clan Ironworks happily sacrifices those generated Pilots to fuel the mana needed to keep the loop spinning indefinitely.
