Post your team you're using in game

[Fett One]

I capped out my team and beat the Elite 4 and this is is what I ended up with

Chesnaught
Meowstic
Dragalge
Aegislash
Hawlucha (HM slave)

Pretty satisfied with my team, especially Dragalge and Aegislash. Real powerhouses

That's only five pokemon. Did you use a sixth pokemon?
