Suggestions for X and Y team

I'm going to be buying a new a copy of Pokemon X and Y and I'm trying to work out my team.

So far I'm planning on using Chesnaught, Blastoise and Tyrantrum but I need suggestions for the rest of the team but I do not want to use any of the following Pokemon as they were on my team for my old copy of Y.

Delphox
Venusaur
Aurorus
Lucario
Sylveon
Greninja

I highly recommend a Drapion, since your team so far is rather weak to Fairy. Plus, he can wipe out Psychic types.

well there's always the ever popular aegislash? it's resistant to fairys.
Now I haven't played my pokemon X in a few months so I'm a bit fuzzy on what pokemon are where but you can get aggron right? that's another good steel type for you.
Some random pokemon that I remember from me and my friends teams: Jolteon, arcanine, Raichu, Blaziken, breloom, bisharp, dragonite, garchomp, togekiss and talonflame.
I hope my rambling helped?
