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.
Best Answer
Because the card pool that's tied to a particular slot somehow incorporates the account name in the seed for the randomization function the game uses for creating your sealed pool, if you're playing on a platform that allows you to change your username, it may be possible to delete the sealed deck data on your platform, change your username, and open new boosters in that slot.
