I have completed the mastery track and am at the part where you get an uncommon card for every 1000xp, last time I couldn't be sure because I clicked too fast, but I thought I did not get my card. This time I am definitely sure I did not receive it. I played an extra game just to make the last of 1000xp and when I finished the game, it rewarded me the xp and gold---but no card.
