Ya know, animals in real life are evolving and adapting constantly to become better survivors in their own ecosystems. I don't see why some Pokemon can't come into a brand new attribute through some form of adaptation that potentially improves their performance/survivability. You could say as a counterargument that if Pokemon can simply adapt into a new type, then it doesn't make sense that they wouldn't change to an existing type, but I think that's the fun of it. Let's pretend that if Eevee really does evolve into a Fairy-type, then it's a completely new form of adaptation. EDIT- Just found this Hide (Move your mouse to the hide area to reveal the content) Show Hide Hide Hide The artists that make these are in desperate need of a graphic designer's help, let alone getting a good translator. When was the last time CoroCoro revealed anything with that kind of background layout? Seriously when?
