Every month or new event or something when we get a new cardback i always have to go through so fricking many pages to get to it to set it as favorite if i like it. There is no like “new” filter and they usually don’t show its name when you get it, just a season card back description. You can search by its name, if you somehow know it. With hundreds of cardbacks in this game, i wonder why there is no easier way to go around this. Irks me every month 
Google is your friend. Im always playing with the new cardback of the month and change it the next one. Just search it.
