Nice to see a Hail team, much better than all the sand and rain
For Jynx, I suggest you use either HP Fire or Lovely Kiss, to put incoming Scizor out of battle, since it can trap or just kill with the appropriate move. HP Fire kills it outside of rain, Lovely Kiss lets you safely escape from it. It also can hinder some other threats, like Latias and CBTar.
For your problem with MoxieMence, I assume the scarved Outrage variant, you can use Blizzard on Dusclops. It survives an Outrage and Blizzard I think KO's after SR damage. Just the sub would be gone then.
The Heatran set I find rather weird. Max SpA investment, yet Lava Plume is the chosen STAB move. I recommend Fire Blast/Flamethrower t kill opponents, instead of having a chance of burning. If you want to keep Lava Plume, put the EV's into Hp.
I also see opposing BalloonTran to be a slight problem, untill the balloon is broken. It kills the snowtree with a Fire move of choice, DNite after SR with HP Ice, Heatran with EPower, Jynx with that same Fire move, so it's bound to take out at least one member of the team. The best thing to do is stall it with SubSplit Dusclops, but when she's gone, you'll lose something.
Hope this helps somewhat :3
