Spirit Island - River vs BP 6

Brandenburg-Prussia 6 as River Surges in Sunlight. Today we're starting (continuing?) a 48 game series in which I will take on every adversary in the digital app with every spirit. Some of these games will just use the base game (like this one), while others include Branch and Claw, the Event Deck, and/or Scenarios. If you have specific constraints on any given matchup that you would like to see, let me know in the comments below!
