Using the Adventure Deck as Divine Intervention
The Adventure Deck is an optional accessory that can change the outcome or complete direction of a session, adventure, or even a campaign. You can play a card that can introduce reinforcements or an angry mob, grant a sudden surge of power points, or give you knowledge about something you might not have otherwise known.
Imagine a setting then where the gods are real. Imagine that when you play an adventure card, instead of rationalizing how realistically something happens, it's instead a very real form of divine intervention. The gods manipulate events and outcomes. They speak to the player characters directly, bestow knowledge upon them, imbue magical power upon them.
Those reinforcements, a band of valkyrie or a flock of giant eagles coming to your aid. That sudden knowledge, a god bestows divine awareness and skill. An attack misses you, a spirit from the realm of the heavens stepped before you and deflected the blow.
With that in mind, I think there's even room for a new player role as one who acts as a god or as the entire pantheon of gods.
