The Yu-Gi-Oh! booster set that never was is finally here! Retro Pack, the lost booster set, was never released in North America. Now, as part of our ongoing anniversary celebration, you can FINALLY fill this missing hole in your collection! Only released overseas, Retro Pack was a collection of vintage cards from the earliest days of the game, made to catch up other countries to the North American card pool. But since it was never released here, these exact cards can be hard to find – until now!
