Ever since Sylveon made it's debut , everyone seems to have been assuming it's a new type and debating over what it could be. I've seen Love, Light, Fairy and in one brief, glorious moment, Lesbain. So why not make a poll to get a rough idea of what the most popular prediction is?
I personally think Light is the most likely. We've already got a Dark type, so it makes perfect sense. (yes Dark is actually Evil in Japan, but Light could just as easily be Good)
