Kyurem-Black @ Leftovers
EVs: 252 HP / 252 Def / 4 Atk
- Dragon Tail
- Ice Beam
This set has insane surprise value an is one of the most dangerous pokemon to face when you have hazards on your side of the field. 125/100/90 defenses are incredible on a pokemon that has more attack than adamant terrakion uninvested. It finds many opportunities to switch in and set up that first sub, and start the vicious cycle. Too many 4x ice weak pokemon are in OU, and this set KOes all of them with no investment, threatening to shuffer the switch in for additional SR damage. Very few things can KO this pokemon, and anything slower can be PP stalled easily. It takes SE hits and can shuffle the opponent's pokemon away. It can "sweep" entire teams with rapid spin support, but you MUST have at least SR on the field. Analytic Starmie with Thunder makes a great partner, removing spinblockers and keeping SR off the field. Forretress provides Toxic spikes support/spikes support(important to get damage on grounded steels) and can sponge any errant draco meteors that threaten to KO this behemoth. Specially defensive Gyarados resists everything this pokemon doesn't, and makes an incredible partner as it lowers attack and makes setting up those substitutes even easier. It doesn't handle powerful stab special attacks too well, but its massive HP stat let it set up in the face of defensive pokemon with ease.
The physical damage calcs are astounding: Literally nothing save banded dragonite outrage KOes more than 75% of the time, so this works as a pretty safe last stop check to powerful physical attackers.
252 Atk Garchomp Outrage vs. 252 HP / 252+ Def Kyurem-B: 284-336 (62.55 - 74%) -- guaranteed 2HKO [see CB terrakion for CB outrage damage calcs)

252+ Atk Choice Band Technician Scizor Bullet Punch vs. 252 HP / 252+ Def Kyurem-B: 234-276 (51.54 - 60.79%) -- guaranteed 2HKO after Stealth Rock

0 Atk Ferrothorn Gyro Ball (127 BP) vs. 252 HP / 252+ Def Kyurem-B: 186-222 (40.96 - 48.89%) -- guaranteed 3HKO (ferrothorn is almost always setup bait. just make sure you don't switch in on leech seed. relaxed nature lowers the power of gyro ball)
Kyurem-B can take special attacks, but Draco Meteors of any kind or Specs Focus Blasts send it running home.
252 SpA Keldeo Hydro Pump vs. 252 HP / 0 SpD Kyurem-B: 106-126 (23.34 - 27.75%) -- possible 5HKO
+1 4 SpA Latias Dragon Pulse vs. 252 HP / 0 SpD Kyurem-B: 344-408 (75.77 - 89.86%) -- guaranteed 2HKO
252+ SpA Hydreigon Dragon Pulse vs. 252 HP / 0 SpD Kyurem-B: 344-408 (75.77 - 89.86%) -- guaranteed 2HKO
I added the Keldeo calc to show that dtail coming off of uninvested 170 Atk is still incredible, factoring in hazards, even keldeo is 2hkoed.
