Kyurem-B went down to OU? Oh and they forgotten Freeze Shock. It eases prediction against stall teams on the CB set. Click Freeze Shock and something will die in a team like Hippowdon, Skarmroy, Blissey, Dusclops, Tentacruel? Faster revenge killers will own you then lol.
Also invest in Defense first please, it helps a lot more and Kyurem-B already has a huge HP stat.
