Change to rewards system
Right now players are rewarded for daily wins and weekly wins. I feel like a daily mission/reward system is a great way to keep players coming back each day, however, requiring wins is a bad idea. This creates an environment of bad behavior and limited deck play because players will build only fast decks with single tricks and then concede quickly if the deck fails or will sit and use timeouts to frustrate their opponent into conceding. My suggestion is to have the wins changed to games played without conceding. I think this will lead to a generally nice play environment and a greater variety of decks being used on a regular basis.
