I have done some research on the Pokemon "Sylveon" and I found some rumors regarding a new type. I have only one thing to say about that: forget it. The only reason Steel-types and Dark-types exist, for instance, was to nerf Psychic-types. The formula for Pokemon is actually quite balanced as it is. Why bother adding a new type? It would only screw up how balanced the typings are. And really. Fairy-type? That's about as pathetic a name as anyone can come up with. If you ask me, Sylveon is going to end up just like Reshiram. Everyone though he'd be some cool new typing when he really wasn't.
