Shiny Ditto in Pokemon Y

I decided to go catch more Dittos to try to find one with a Calm nature, and found a Shiny ditto instead. I'm so glad I was actually paying attention to my DS, since it had the imposter ability so it transformed into my non-shiny ditto at the start of the match. That makes this my 6th shiny ever, the others being Caterpie, Spiritomb, Gyarados (not talking about the 2nd gen one, talking about the one I caught in Pearl while looking for a Starmie), Roselia, Pelipper, and now Ditto. It's max IVs turned out to be attack and speed. I could actually probably EV train this Ditto to use in battles.
