Banks of Anduin has a 3 Progress value or whatever. 3 Northern Trackers quest, putting it on top, you reveal a card, it's Banks of the Anduin, and so on. I realize 3 Northern Trackers is unlikely, but even with 2 you're doing it every other turn and it's still INCREDIBLE.

Spirit can't win the scenarios in combat phase so this is one combo spirit can use to complete the scenarios with a different way.
