So as someone who completely skipped over Gen 5, I wanted to have my first playthrough of X with a team of pokes only from Gen 5 and 6 since I have not been exposed to any of them. Would the following team work at all, (ingame team but would also be cool if they could be competitive) i've checked all of them out and these guys came out as my favorites.

Greninja (Protean)
Golurk
Hydreigon
Goodra
Noivern
Aegislash
