In Magic 2014, you are given two slots for sealed deck play. Each slot corresponds to the random card selection you get when you first use the slot, and there doesn't seem to be a way to delete or free up this slot so you can generate another random set of cards.
Is it possible, through out-of-game means, to reset your sealed deck slots? Like deleting and redownloading the game, deleting the saved game somehow if it exists, etc.
