Hanabi Blast

Deadeye Navigator

Torrential Gearhulk

Storm-Kiln Artist

Panharmonicon

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.
