I really don't see the point of Jolteon in this team, I can actually call it a "filler" because the rest of your pokemon actually seem to be doing a job. One a quick note, keep the Lucario, otherwise Cresselia stalls you to death, and so do other stall team and Bulky Pokemon in general. I would really see Bronzong working as the lead better, RestTalk can be a option. MixApe can be problems here, the HP Ice variants can be scary, but don't fear, with Bronzong as lead, Jolteon has now becomed useless, and can be actually be switched to his water brother, Vaporeon, who unlike Jolteon, will provide a counter to MixApe and Gyarados, with Surf / HP Electric, and Wish to keep your sweepers healthy.
If you don't feel safe with 2 Bulky Waters, you can run a Gliscor over Swampert with SR, and actually have something for Lucario and Heracross. That's all I have to say, you seem to know what you are doing anyways.
