Add SubRoost Kyu-B as a counter as it avoids the OHKO from +2 Sludge Bomb even after SR, and OHKOes back with Ice Beam after SR and 1 LO round. Every other Kyu-B set is a good check as long as SR is off the field
That would also extrapolate to normal Kyurem too.
Whatevs sig. QC member for OU and Ubers, VM me for a look at your analysis. Just make sure it's good.
Also, if you want me to rate your team (OU/DW OU/Ubers), give me a VM. If I don't rate it, it's either 1) it's so shit it's too much trouble, 2) I'm busy, or 3) the team is fantastic and I have nothing I can suggest to you. You should be able to recognise which one.
