This team has a huge weakness to Water-types that use Ice Beam as a coverage move. Pokemon such as Simipour, Ludicolo, Samurott, and Golduck can hit every member of your team super-effectively besides Zangoose, who is extremely frail. To fix this, I would suggest replacing Altaria with
Specially Defensive Lickilicky, who can take multiple hits from the Pokemon listed above and stall them out with Wish. Like Altaria, it can support the team with Heal Bell.
For Camerupt, I would highly suggest running an
Offensive Rock Polish set. The current set is a bit inefficient since you're running three attacking moves and Rock Polish with a defensive spread. You already have two special walls in Probopass and Licklicky, so running an offensive spread of
40 HP / 252 SpA / 216 Spe with a
Modest nature wouldn't hurt your team that much. I would also use
Life Orb over Leftovers and
Fire Blast over Lava Plume to hit as hard as possible.
Hidden Power Ice should be used instead of Hidden Power Grass because it allows you to hit Altaria and other Dragons harder.
Probopass' nature should be
Calm since Bold raises Defense; I'll just assume that was a typo.
Exeggutor needs
84 Speed EV's (taken out of Defense) to be able to put up a Substitute before Alomomola can Toxic it. This is very important since Exeggutor is your most effective way of dealing with Alomomola. You could also consider dropping Giga Drain for Protect, which helps you recover more with Leech Seed, stall for more Sitrus Berries, and makes dealing with Choice Band Braviary and Emboar a lot more easier. Giga Drain doesn't really help you beat anything that Leech Seed can't anyways.
Golurk should run either
44 Speed EV's to land a hit on Lapras and Weezing before they can hurt you or
176 EV's to outrun max Speed Golem. This is optional since Golurk has very nice bulk with max HP.
Good luck with the team!
