OK, I was asked a question today about unique characters and I feel like I know the answer but I can not find it in any rule books. I know the rule book states that you can only have 1 unique character of the same brigade and that if they have different pictures in different brigades they are legal. But all of the rule books were created before Priests came out and reprinted Prince of this World, King of Tyrus, King Hezekiah, and probably more.
So what is the ruling on having the same unique character with the same picture but different brigades in the same deck? Not only do I want a ruling but I need a place to verify this, if there isn't one it is way to late to get it in the rule books and needs to be placed somewhere for everyone to see. Thanks!
