After playing this game for about a week, I've noticed that there are apparently hundreds of URs, and the vast majority of them can only be pulled from premium summons and the like, unless I'm mistaken. As a veteran of card based collection games, there has always been a way to get the specific card you want, whether you craft it from materials, trade for it, buy it specifically, etc. However, there seems to be no way of doing something like that in this game. In short, if I were to scour the entire list of cards in this game and devise a list of all the cards I specifically wanted for my unit, would I have to rely on the luck of the draw from premium summons and the like to get them, in a game where I am unwilling to spend money? Or is there any other way to get cards listed as only being available through premium summons and the like?
