Let's say that suddenly this evolution thread is released by Nintendo. I know the art isn't great, and this is just going by the actual designs. If you think they're shit, thats ok, not everyone will like the official chain anyway.
Forget all that, because I want to know, what would you do if you were stuck with this. Which, if either, would you train?
