So the team in going for right now consists of

Azumaril

Talonflame

Ferrothorn

Excadril

Gardevoir

And for the last poke I was thinking either hippowdon for sand stream or togekiss/ blissey for the status moves. I'm new to Pokemon pvp and this is my first attempt at making a decent team for pvp. I've tried to come up with the most balanced toeam I could to try and check all of the main problems but I'm sure I'm missing something. Also I was thinking of maybe trading out Talonflame for infernape for the fighting type to take down blisseys. What do you guys think?

Azumaril, Talonflame, Ferrothorn form a very strong core already. I wouldnt recommend keeping gardevoir as its missing a fairy stab move and could really benefit from mega evolving. If you could swap out garde for blissey, keep exca and get hippo i think you would have a very potent team. Blissey will act your status sponge and sp atk tank while hippo and ferro will be more than decent physical defense tanks. Azu, talon and exca will provide you plenty of fire power and coverage as well. My only concerns would your lack of sp atk damage, in which case you could swap either azu or talon for sp attacker such as togekiss. You may also have trouble with other azu though ferro fixes this to some extent.
