I started playing this again a few months ago, because I found out that they were giving old players free "catch up" packs that contained up to 50 cards, based on how many cards you had from the latest set. So I'd say this is a 5 star game if you can reliably get the cards, but seeing as the game's monetisation requires that you can't, I know that this will be an outlier and that by the next rotation I'll be back to being unable to get the cards for a viable deck. (I know that you can dust cards to craft others, but that's so painful in a digital card game that it shouldn't even be an option. If you have to get rid of most of your cards to play just one class, how is that fun?)
