I primarily am not going to suggest changes to your team because you'll obviously prefer to keep the most you've chosen for your own reasons. I'll instead recommend changes to the sets.
Chandelure could use something other than dark pulse, which is redundant for the most part. Try substitute, or HP Fighting or Grass if you're lucky. Flamethrower is also more consistent and can get fairly powerful if you remove white herb for an item that actually boosts power, like that life orb (Bisharp can use black glasses for a similar effect because most of its moves are dark type anyway) or a charcoal if you wish.
Aqua Jet is really useful on Azumarill, and iirc doesn't need past gen breeding, but I could be wrong. Aqua tail is kinda worthless if you have waterfall which is more consistent and has a better side effect.
Gogoat really likes EQ, aerial ace is meh. You could always try a flying type.
And now, assuming you are open to a change of mons as well, a fast flying type or so isn't bad for your team. Noivern is good there, gets nice moves albeit at a high level. You also have quite enough firepower, lol, so getting rid of fire coverage on some of your mons might be useful. In that case, Magnezone is better as a bulky electric type than eelectross, and offers more utility in general besides being stronger. If you keep eelectross, ditch one of the electric moves for something that gives utility. TWave support can be nive with your general slow team, and can also help spread status for Chandelure's hex. Getting a Metagross or a Bronzong may also help; Bronzong makes a fine Trick Room user if you like that. Also though it requires breeding, Roserade is worth considering. Tangrowth is also a bulkier grass type than gogoat in general. DDrantrum is a fine choice.
