Off the bat I notice that your Kyurem has a Careful nature, and I am sorry to say that this lowers his SAtk stat, which is the stat you appear to be using the most. The best thing I can do is recommend you find another Kyurem, probably by trading, and get one with a better nature. I might also add that at level 70 it won't be doing much in any battles against your freinds, assuming those battles would be at level 100. Either way I suggest you get it to level 100, I recommend you replace Psychic with Focus Blast, and Glaciate with Ice Beam. Make his item either a Life Orb or Leftovers. If you want to run a physical set to bypass the nature lowering your SAtk, run Outrage, Stone Edge, Shadow Claw, and Dragon Claw.
