Hanabi Blast + Deadeye Navigator + Torrential Gearhulk + Storm-Kiln Artist + Yarok, the Desecrated

Hanabi Blast

Deadeye Navigator

Torrential Gearhulk

Storm-Kiln Artist

Yarok, the Desecrated

How it works

1. Activate Torrential Gearhulk by paying 1, blinking it.
2. When Torrential Gearhulk enters the battlefield, it and Deadeye Navigator's soulbond ability trigger twice.
3. Resolve both Deadeye Navigator triggers, repairing it and Torrential Gearhulk.
4. Resolve a Torrential Gearhulk trigger, casting Hanabi Blast from your graveyard without paying its mana cost.
5. Storm-Kiln Aritst triggers, creating a Treasure artifact token.
6. Resolve Hanabi Blast, dealing 2 damage to any target, returning Hanabi Blast to your hand, and then causing you to discard Hanabi Blast.
7. Repeat from step 4 one additional time.
8. Activate both Treasure tokens by tapping and sacrificing them, adding 1.
9. Repeat.

This looping engine relies on Torrential Gearhulk casting Hanabi Blast directly from your graveyard, which is fueled by the mana from the Treasure tokens generated by Storm-Kiln Artist's magecraft ability. The entire loop is sustained by repeatedly blinking the Gearhulk with Deadeye Navigator's soulbond ability, an activation cost conveniently paid for by sacrificing those same Treasures. Meanwhile, Yarok, the Desecrated supercharges the enter-the-battlefield triggers, ensuring everything scales exponentially into a devastating cascade of infinite damage and artifact creation.
