Hey man i got your request!
This team is extremely solid and the use of SubRoost Kyurem and Expert Belt Thunderous-T is really awesome. I don't really find any problems with this team except Mamoswine can be a little bit annoying being able to gain super effective coverage on 5 members of your team with Superpower / Earthqauke / Ice Shard / Superpower / Icicle Spear. However with proper play you should be able to work around it. Trying out Taunt>Thunder on Thunderous is something i think you should play around with. One of my friends used to use Expert Belt Thunderous-T with Taunt and it shuts down a lot of Pokemon trying to set up hazards or boosts. With Volt Switch you can switch out on a Taunted opponent and bring in one of your Pokemon that can abuse this oppurtunity. This change is just something opptional as i can definetly see why abusing Thunder is a good idea.
Good luck with the team i hope i helped!
TL:DR
