IMO, since dice rolling is not part of the Fallout world, and Mr House is not one of the face commanders of the PreCons, I wouldn't expect any substantial dice rolling cards. They might include a 2-5 cards to support Mr House as one of the sets mythics, but I wouldn't think more than that. But, I guess we'll see for sure when the rest of the spoilers start hitting!
I'm excited to build a Mr House deck
