Wel if they did make this one star they only be one in each deck only an it has to be prity low power if it has a ability. if no ability would have high power. an the damige would diffre between the clans bounes an the cards ability. but probly no
I would be okay with it if it didn't go against one of the main ideas of UR (and RPGs in general) - that characters from clan become stronger after winning more fights. One of the main draws of UR when you're a beginner is finding out what artwork your card will get when it levels up, or what the new ability/stats are. Having a 1* fully-evolved would ruin that fun.
