I was thinking about replaying my copy of Y sometime since that's around when I started losing interest in newer pokemon stuff, what are some fun Kalos-centric pokemon to try out?

Right now I had something in mind like Delphox/Diggersby/Florges/Dragalge/Avalugg/Noivern

I don't know much about the Kalos mons since the only time I played Y the only Kalos pokemon I used was my starter and Aurorus.
