Wow really? Cool. Um I don't know why starters there are.
Think of 5 of your favorite pokemon. You get to pick one starter from gen 6 anyhow so if you'd like to fill your team out, we can make eggs of them so you have a full team for your adventure. Assuming you want to do that, that is. I did it for White 2 it was a lot of fun raising an entire team. I had:
Charmander, Joltik, Oshawott, Deino, Turtwig, and Beldum
