Your card deck shows your feedback as the cards are the magic you know or the creations you can stimulate in your row to overcome your opponents.
That is still something to watch out for and I hope that their quality control is able to keep issues like these to a minimum, as it would be very unfortunate if these loose dice wound up damaging the Promo card, which has little more to protect it than a thin plastic wrapping
