Hey there! comparing with hearthstone is tough. We don't have the same budget so we can't even begin to create the same production values. You're right, they did an excellent job but we purposefully tried to do something a bit different. Our cards are a lot less physical, but then they are also an abstraction of ingame interaction and not representations of in world physical cards, as they are in Hearthstone ;)
As for more screenshots: I will post more stuff later this week and will try to include some info on that and the combat system then.
