I'm addressing no-one in particular, but if you think Kyurem-B should be tested in OU, you need to get your fingers off your keyboard and onto your mouse to play more Pokemon. Seriously, the arguments that I have seen around the place are making me either laugh or shake my head profusely. Here's what I've seen:
Kyurem-B has a chance in OU because:
1) It has no movepool
2) Ice-typing an Stealth Rock weakness
3) It is "slow"
Now let me address these:
1) It has no movepool - Does it really need a movepool outside of Outrage and Fusion Bolt? Off 170 Base Attack, you don't need anything other than those two moves. If you put on a Life Orb onto this thing, there's also Ice Beam and Hidden Power to murder whatever's left. No movepool is only applicable when the moves in whatever movepool do not fit the Pokemon's needs. Wobbuffet has one of the tiniest movepools ever, doesn't stop it being amazing. 48.76% - 57.43% is how much Choice Band Outrage does to standard SpD Jirachi. Have a think about that.
2) Ice-typing and Stealth Rock weakness - Again, I love how people put forth arguments that make other Pokemon bad to make the Pokemon they are analysing look bad. It's pretty much as silly as saying "grapefruit tastes bad, grapefruits are fruits, so therefore all fruits taste bad". Yes Ice/Dragon is a relatively poor defensive typing, yes it is Stealth Rock weak, but what about everything else? Have we forgotten Ice and Dragon are two of the best offensive typings in the game? Yes, they are redundant, but with Kyurem-B's stats, it seriously doesn't matter at all. Ho-oh is 4x Stealth Rock weak, Rayquaza is also 2x Stealth Rock weak. Do they care? Probably, but there's no way in hell we're testing those two, and the same goes for Kyurem-B.
3) It is "slow" - 95 Base Speed is not slow. I know it is slow compared to many other Pokemon in OU, but there many others slower than it. It's going to be likely that you have at least a couple of Pokemon that are slower than Kyurem-B on your team (or faster, but cannot kill Kyurem-B) which it can come in and go "WTF BOOM" and kill something on your team. Even then, it can run a Scarf set and clean up lategame if it needs to.
I'm not even going to bother talking about Kyurem-W, because there's no point. I've used it in Ubers and there is nothing that can stop up to this thing ever, don't even think about OU.
