This section (as the notice says) is for questions about the forums rather what Pokemon you should use. Try the In-game Team Help section, and in particular the Questions thread sticky that is there.
The Pokemon choices seem fine there, although do note you have two dark types and three fighting types there. Just vary up the moves your Pokemon have (e.g. not 3-4 moves of the one typing on each Pokemon for later game play if possible).
Anyways, closed as this doesn't fit here; if you do want more advice try the places I linked above.
