How to unlock all cards in MTG DOTP 2013/14/15?

Hi, everyone!
Does anyone know how to unlock all cards and decks from any of the "Duels of the Planeswalkers" games, mainly the 2013/14/15 ones?
I'm looking for a way to unlock all the cards and all decks without having to grind through the story/campaign mode, so I'd appreciate the help.
I remember seeing a method for this on this forum a long time ago, but I forgot what the process was to make that happen.
Would anyone by any chance know how to achieve this? What tools, or scripts, or whatever do I need to do this?
