A big problem with this game is that since they want you to keep coming back daily, it takes too long to play. Seesions of 45mins-1hr aren't uncommon. Yes you can skip matches with auto play, but the AI who plays for you just plays random cards instead of your best ones. It's just not very well thought out
There are some things that should be allowed like the symbol for CND, it only accepts 'peace' and not 'cnd'. I genuinely had to look that up to see what it would accept.
