Top 8 at the 2007 Southeast Regional Championship Running a rogue Flygon ex LM/Delcatty PK deck, I was well on my way to Top 4 when I got stopped by a Pok-mom running the Safeguard Banette from Crystal Guardians (yes, I too know the pain so many of you faced when you lost to quad Sigilyph DRX decks)

If your opponent has an exerted Character, you may exert one of your characters to challenge them
