Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Hey, MrCookie, thanks for entering the Dark Horse challenge! Unfortunately, Porygon2 has already made it to the Hall of Fame this month, so you need to find another Dark Horse to participate.
Sorry for the inconvenience, and I hope you enjoy your run!
