Ashton found his old Yu-Gi-Oh cards and deck and decided to teach the game to Sonic and the mane six, but something goes wrong and an old enemy returns with an ancient Egyptian artifact and transforms Sonic and co, as well as five of the mane six and multiple ponies, towns and cities into Yu-Gi-Oh cards and most are sent around the world as well as space and time! It is up to Ashton and Twilight to obtain all the cards and retrieve the artifact to undo all the damage.
