Something for me to consider, for sure. :)
For now, I have EV trained my Froakie. That's four Dark types in the bag; one Shiny 5IV, three at 6IV. Anything extra now will just give me juggling options, but sooner or later, it will be necessary to actually level up the team to learn some moves (possibly exempting Froakie, whose moves will be TMs, but I have to get to Greninja anyway). Not to mention cloning it, which will be my second-ever trip from X into the Power Saves.
