I was wondering if it was intended that Robert Baratheon of the Core Set has no "King" Trait.
Given that he even has a crown on his head in the illustration and that of all the other "Kings" in ASoIaF he is one of the more legitimate ones.
I then thought maybe its an error and looked in the erata and i even found an entry for that card - BUT its just that the cardnumber is wrong.
But he works well with other Baratheon Kings this way as he doesn't stand in their way.. for example Renly baratheon: "Renown.If Renly Baratheon is the only House Baratheon King character in play, he gains: "Reduce the cost to play other House Baratheon characters by 1."
