Tried this out last night and loved it! I used the 5e tarokka deck and had each high deck card trigger a specific encounter, event, landmark, etc. themed on the card. When I do this again, I'll also add themed fluff for each suit, and completing a suit will reveal a major area based on that theme. That way players could actively pursue matches in that suit if they like the clues they've discovered. All in all, I love this simple supplement and wish I found it sooner! Thank you!
