Hi nel, this is a very cool team!
I really like the use of priority in this team!
The first thing I'd suggest is a particular set of Ninetales: invest into SpDef with 96 evs in speed to outspeed adamant Mamoswine and to get more support aganist toed with the addition of pain split as pseudo recovery to increase the staying power of your weather changer.
Now I have noticed a big weakness to Jellicent: Scizor, Lucario, Kabutops and also Ninetales are completely walled from the jellyfish also will block your spinning, so I suggest you to give Crunch > Bullet Punch to Lucario, so you can get out that annoying Pokemon and also hit even Slowbro.
I know that Kabutops is an important point for your team, but I noticed a little weakness to the Drag mag so I thought I'd tell you to put Max Atk Donphan with Ice Shard to help this potential problem.
About Scizor, for the SDOrb set i always give this Evs spread for outspeed Modest Magnezone EVs: 40 HP / 252 Atk / 216 Spd
Hope this helps friend , ludvisc'd
