Well, perhaps I am good at intuiting stuff but I never had problems understanding what a card did... it said on the card. And naturally during my first games I had to read every single card, later I found the wiki and simply read every single card.
What interests me specifically is exact turn order, for example turn begins, you draw a card, then you have a main phase to play cards, then you attack, then your quanta is produced (pillars, pendulems, and towers first then your mark), then your weapons attack and other permanents heal you, during your opponents turn your purity/poison occurs during the attack phase. (at least this is how I see it right now, I'd be delighted in a precise turn order)
Just my thoughts. As I have read the wiki and knew the skills and abilities already.
