So I have just started getting into trying to play competetive with the easy EV system that is Pokemon X/Y.
I recently hatched myself a shiny Scyther with these nature/personality/IV
Adamant Nature (+atk, -sp.atk)
Personality (Likes to trash about)
IV: Above Average.
Would you still use it for competitive? I would assume not, but the shinyness is what makes the thing even more pimp, I do after all have great personality and nature.
