2Spooky public event with the new cards from Shadow Specters.
Q: What is the NightScare Before Christmas Tournament? * UPDATE *
A: Our holiday season has been invaded – by ghosts and ghouls!
Come celebrate the clash of two holidays in a new, one-time-only Tournament Format for the Yu-Gi-Oh! Extravaganza at Atlantic City, NJ.
Advanced Format
All Monster Cards in the Main Deck and Side Deck MUST have “Ghostrick” or “Vampire” in the title. (Older “Vampire” cards, like “Vampire Lord” and “Vampire Baby”, can be used. Also, you can mix & match “Ghostricks” and “Vampires” in your Deck – you don’t have to choose one or the other.)
There are no additional restrictions on Spell & Trap Cards.
Exception: “Vampire Hunter” (SHSP-EN034) from Shadow Specters cannot be used.
