I played two games of it 1v1 against my roommate last night, and it's pretty fun. I won the second one when I had 3 blue districts and opted to put Bishop facedown on the table when I saw that Assassin was missing from the hand. My roommate assassinated the nonexistent Bishop, and I won that round.
