Hey Butterfree cool team! FLCL covered a lot of what I was gonna say so all I have is some small changes here and there. So lets get started shall we?
Firstly I would use
Earth Power over Power Gem as it lets you hit opposing Probopass for super effective damage. Volt Switch lets you hit everything Power Gem hit for the most part and lets you get switch initiative against Braviary and company.
Secondly I suggest
Dragon Pulse over Draco Meteor on Altaria if you decide to keep it.. Since you're using a more defensive set it doesn't make any sense to use a move that decreases your special attack and makes you switch out. If you really want to use Draco Meteor I would suggest switching to a Specs Altaria set.(I'll provide the set at the end).
Next I really, and
I mean really suggest not using No Guard Golurk. It sounds great and all but you're decreasing the power of Ice Punch, Drain Punch, and Shadow Punch just to boost the accuracy of DynamicPunch and Stone Edge. And Stone Edge's coverage is provided by a combo of Ice Punch and Earthquake.
And lastly, I suggest using a
4 attacks Zangoose over the Swords Dance set. Swords Dance Zangoose is incredibly hard to set up and you are better off with the immediate power and coverage that 4 attacks grants you. It also lets you use
Quick Attack which is actually very useful for picking off weakened Cinccino's which can do a number to your team currently. Also
Night Slash over Shadow Claw, its very minor but its better to use Night Slash and hit a Swellow or Cinccino on the switch than let them switch in freely with there Ghost immunity. Also there are no good justified users besides Absol which boosted Night Slash and Quick Attack take care of pretty well.
Thats all I have! Hope I helped and good luck with the team!
Sets:
Wow, I just now realized I put LO Zangoose. Thanks for correcting me AA, I did actually mean Toxic Orb 4Atk Zangoose. That was my fault.
