I can no longer open a few of my standard decks. It goes to the waiting for server screen and stays there. Unfortunately, I don't have a list saved with the particular cards in the deck, but it was Green/Blue/Black. Curiously the other deck I could not open was Black/Green and had overlapping cards. Lilianna of the Veil, Mosswood Dreadknight and Glissa. I was able to open other decks, such as domain and a gladiator deck.
