Deadeye Navigator

Plundering Barbarian

Panharmonicon

How it works

1. Activate Plundering Barbarian by paying 1, blinking it.
2. When Plundering Barbarian enters, it and Deadeye Navigator's soulbond ability trigger twice.
3. Resolve both Deadeye Navigator triggers, repairing it and Plundering Barbarian.
4. Resolve both Plundering Barbarian triggers, creating two Treasure tokens.
5. Activate both Treasures by tapping and sacrificing them, adding 1.
6. Repeat.
