Very nice team. There are only a couple of suggestions I can give you that I think would help improve the team. First, I'd definetly get rid of Fire Fang on Garchomp. Fire Blast IS a better option even with a Jolly nature, but still leaves Garchomp as pure setup fodder. Since you already have Magnezone to deal with the things that Fire Fang/Blast are targeting, I'd recommend Stone Edge to give you an easier time against opposing Volcarona, Tornadus-T and Thundurus-T. Rock Slide is weaker but more accurate, and still gets the KOs against the therians after SR damage.
Next, as many others have said, I'd replace Psychic with Psyshock on Starmie. Not for combatting the pink blobs, at it'll still do pittance, but for taking out +1 Keldeo and Terrakion in the sand.
Finally, and I hate to say this, but I'd replace Kyurem with a Dragonite. It gives you an easier time against Sun teams, gives you a second Fighting- and Ground-type resist (I think that all teams should carry at least two), a far better chance against opposing Keldeo and valuable priority. Keeping Multiscale up shouldn't be too difficult thanks to you having a spinner. A Choice Band set is extremely powerful and still viable, but I couldnt help notocing that you don't have any setup sweepers, a win condition you could say. Therefore, you may also want to give the Dragon Dance set a spin. Magnezone support is aldo incredibly valuable if you choose to run the DD set.
So yeah, big props on using Weavile and Bronzong so effectively, you've mafe me want to try them out :)
