Hanabi Blast

Deadeye Navigator

Spectral Arcanist

Storm-Kiln Artist

Panharmonicon

How it works

1. Activate Spectral Arcanist by paying 1, blinking it.
2. Spectral Arcanist enters the battlefield, triggering itself and Deadeye Navigator's soulbond ability twice.
3. Resolve both Deadeye Navigator triggers, repairing it and Spectral Arcanist.
4. Resolve a Spectral Arcanist trigger, casting Hanabi Blast from your graveyard without paying its mana cost.
5. Storm-Kiln Aritst triggers, creating a Treasure 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.
