Relaxed/Bold Nature
- Substitute
- Roost
- Dragon Tail
- Ice Beam
Behold the premiere defensive wall of OU. When you think about Kube, the first thing that comes to mind is that 170ATK stat, and the second thing is outrage. It pulls off many mixed and choice sets well, but few(almost nobody) are prepared for a purely defensive sub shuffler. The first two moves make keeping Kyurem-B alive and healthy very easy. Roost helps mitigate the SR weakness which shaves away a quarter of the black dragon's health, while Dragon Tail allows the nigslammer to force cowardly opponents to take even more damage as they switch out fearing a 4x effective ice beam or a powerful dragon tail on their frail pokemon. Uninvested, Kyurem-B still has incredible offensive stats, rivaling invested starmie and adamant terrakion in one set. Ice Beam mauls pokemon weak to it and assists with Ferrothorn slaying.
You can go with a relaxed nature to retain special defense, as this set is
slightly frail on the special side. (nothing barring draco meteor or specs focus blast will ohko). Relaxed nature makes whittling down the PP of gyro ball even more chill, and you'll find that you're even able to stall out stone edges and fish for misses due to Kyurem's bulk. Forretress makes a great defensive partner, spinning away rocks while keeping them on the opponent's side of the field. Without rocks, kyurem-B becomes much less intimidating. Starmie with analytic and thunder easily disposes of jellicent, it's only check as a spinner, and makes a terrific defensive partner, resisting steel and fighting. Gyarados makes a strong offensive partner, lowering the attack of opponents and sponging powerful fighting/steel attacks, while kyurem-b makes the perfect switch in to obvious thunderbolts and such.
Kyurem vs Kyurem-Black: I find that the nature of attacks hurled at the dragon/ice typing are usually physical, therefore the addition 10 base defense of Kyurem-B and increased D-tail damage are of greater utility than the increased SpA and ability in Pressure. This pokemon is meant to set up on slower walls or switch into things that pose no threat and get up a sub, and start clicking dtail to stall out other mons. Once it has a sub up, it can spam roost/sub repeatedly and stall out faster pokemon with powerful moves that do >50% damage. Pressure is without a doubt the better ability on this set, but I've found myself being able to stall out stone edge/CC pretty well without it. Of course, if there are multiple pokemon you need to stall out, kyurem might be a second option, however you will sorely miss the power in dragon tail and the 10 defense you lose. Furthermore, Kyurem-black has much greater surprise value as a subroost shuffler. It's not meant to stall PP so much as it is to force switches and rack up hazards damage. People usually expect a powerful physical attacker, or a fairly bulky sub/3attacks mon, but get demolished by the physical god that is Kyurem-B.
