Ninfia being ghost or dragon seems odd. I mean, it's got bows. I could see the flying, as the ribbons would billow in the wind and "flying" is more "air" anyway.
Of course, Eevee evolving into a normal type seems wrong. Also, I'm still waiting for the Eevee that evolves into a ghost-type when it looses a battle because I think it would be quite humorous.
