You have a lot of good Pokemon, but the movesets only need a little bit of tweaking. Plus, we need natures and EVs for us to really take a look at your team, so include those next time if you want any real answers.
Unfezant doesn't need three Flying-type moves. Roost, Fly/Pluck, Return, and some kind of filler would work fine.
Samurott also doesn't need three water-type moves. It can Megahorn, Night Slash, Revenge, and lots of other cool stuff, so let'em have a hand at a couple.
Meinshao is almost perfect, but doesn't really need Aura Sphere. For in-game, this could be beneficial, but over Wifi, it's just a waste. Just try some coverage filler such as Bounce or Poison Jab, for that extra punch.
Chandelure's good to go.
Bisharp's good to go too.
Flash Cannon and Draco Meteor probably aren't the best choices for Hydreigon. Flash Cannon has horrible coverage, and Draco Meteor just weakens all of your attacks as you go along. Maybe reteach it Dragon Pulse to replace Draco Meteor, and Surf to replace Flash Cannon.
Overall, not a bad team, but we don't really have any specifics, so for now, just fix up some of the movesets. Two or more moves of the same type usually isn't orthodox.
