The Advanced Crystal Beasts from Yu-Gi-Oh! GX make their long-awaited debut! These sinister forms of the Crystal Beasts come with advanced versions of their original powers, like Advanced Crystal Beast Topaz Tiger, which gives its ATK boost to ALL your Crystal Beasts - and lowers the ATK of your opponent's monsters, too! The original "Crystal Beast" cards and related cards also work with the Advanced Crystal Beasts, so you can power up your Structure Deck: Legend of the Crystal Beasts even further!
