Deadeye Navigator

Panharmonicon

Prosperous Innkeeper

How it works

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