Since the introduction of the free card draw, I've been sort of forced to acquire lots of champions in order to do the daily assistant quests. The reason is that the free card draw doesn't reset until I pick up the card, therefore forcing me to pick up a champion or miss out on the next free card draw & daily assistant points. (Since you can't move on to the next draw until you pick the card up).

Is there a way to avoid adding a champion to the pool & reset the card draw without picking up the card so I can do my next daily free draw? If not, how do I delete the champions I don't want from these daily draws?
