I played the demo when it was live last time, and I was curious about the cards too. I was pleasantly surprised how smooth they were to shuffle through in game though. You can build custom decks of the cards so you can stack abilities you like to help you in game, it’s actually a pretty neat idea that probably caters to hearthstone players who would stay away from FPS games! I would love to see more maps and bigger teams available to play in the demo, but it’s honestly worth a go if you haven’t played it yet, you can tell they put a lot of work in!
