Reminder that Pokemon Black and White awarded you with medals for mono-type teams beating the Elite Four. If that's the case, what mono-type team would you assemble in X and Y?

I'm thinking mono-water. Froakie, Squirtle, Clauncher, etc.
If I could access any generation's Pokemon though, it's definitely Rock type. Aggron is the best.

(Also, they rewarded you for beating the Elite Four with a single Pokemon)
