Thirteen is the most sinister number of all. So in 2013, Halloween will be a truly special moment, at least in the Yu-Gi-Oh! Trading Card Game! 
Release Date: November 7, 2013

This year, your monsters will be able to ask for Trick or Treat well beyond October 31. Thanks to the specters and ghosts that will be included in the year-end expansion: Shadows of the Ghosts!

For Duelists who want to scare their opponents, Vampires are the central theme of this set, featuring a complete series of new Vampire monsters, spells, and traps (the first previewed by the Vampire Kingdom preview card, coming in the Judgment of Light Deluxe Edition).
If you want an even more extravagant Halloween experience, take a look at the tricks and treats of the adorable Ghostrick monsters.
