I've made some calcs with the LO mixed set, and I got nice results:
252+ Atk Life Orb Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Azumarill: 458-541 (113.3 - 133.9%) -- guaranteed OHKO
(458, 463, 468, 476, 481, 486, 491, 497, 502, 507, 512, 517, 523, 528, 533, 541)
While the only attack azumarill can fire is Aqua jet, wich does only 10%
252+ Atk Life Orb Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Togekiss: 398-471 (106.4 - 125.9%) -- guaranteed OHKO
(398, 403, 408, 413, 419, 421, 426, 432, 437, 442, 445, 450, 455, 460, 465, 471)
Togekiss have no way to fight back
252+ Atk Life Orb Teravolt Kyurem-B Iron Head vs. 4 HP / 0 Def Mega Gardevoir: 434-512 (156.1 - 184.1%) -- guaranteed OHKO
(434, 439, 445, 450, 455, 460, 465, 471, 476, 481, 486, 491, 497, 502, 507, 512)
252+ Atk Life Orb Teravolt Kyurem-B Fusion Bolt vs. 4 HP / 0 Def Gardevoir: 270-318 (97.1 - 114.3%) -- 81.3% chance to OHKO
(270, 273, 277, 279, 283, 286, 289, 292, 295, 299, 302, 305, 308, 312, 315, 318)
Mega gardevoir stands a problem for cube if its already evolved, this one relies in prediction, but if Gardevoir is in its normal state, theres no chance,
252+ Atk Life Orb Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Mega Mawile: 157-186 (51.6 - 61.1%) -- guaranteed 2HKO
(157, 159, 161, 162, 165, 166, 169, 170, 172, 174, 175, 178, 179, 182, 183, 186)
0- SpA Life Orb Teravolt Kyurem-B Earth Power vs. 252 HP / 4 SpD Mega Mawile: 185-218 (60.8 - 71.7%) -- guaranteed 2HKO
(185, 187, 190, 190, 192, 195, 198, 200, 203, 203, 205, 208, 211, 213, 216, 218)
The set have problems with Mega Mawile, altough it can seriously harm it
252+ Atk Life Orb Teravolt Kyurem-B Outrage vs. 252 HP / 0 Def Conkeldurr: 356-421 (85.9 - 101.6%) -- 50% chance to OHKO after Stealth Rock
(356, 360, 364, 370, 374, 378, 382, 386, 390, 395, 399, 403, 407, 411, 415, 421)
Needing SR support, but you can use CB if you really fear conkeldurr
252+ Atk Life Orb Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Scizor: 191-225 (55.5 - 65.4%) -- guaranteed 2HKO after Stealth Rock
(191, 192, 195, 198, 199, 201, 204, 207, 208, 211, 213, 216, 217, 220, 222, 225)
252+ Atk Life Orb Teravolt Kyurem-B Outrage vs. 252 HP / 0 Def Scizor: 170-201 (49.4 - 58.4%) -- guaranteed 2HKO after Stealth Rock

Cannot switch into cube, as not even CB Bullet punch ohkoes
0- SpA Life Orb Teravolt Kyurem-B Earth Power vs. 252 HP / 0 SpD Rotom-W: 166-198 (54.6 - 65.1%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
(166, 169, 172, 172, 174, 177, 179, 179, 182, 185, 187, 187, 190, 192, 195, 198)
As most rotom-w uses Defense EVs... Just need to watch for WoW, passable if you have a nice cleric, probably your opponent will sacrifice Rotom to leave a burn in Cube.
252+ Atk Choice Band Teravolt Kyurem-B Outrage vs. 252 HP / 252+ Def Rotom-W: 271-319 (89.1 - 104.9%) -- guaranteed OHKO after Stealth Rock
(271, 274, 277, 280, 283, 286, 289, 292, 297, 300, 303, 306, 309, 312, 315, 319)
Or if you use Choice Band, wich is my prefered item, because most times it will be switching after an attack anyways
Kyurem-B @ Choice Band/Life Orb
252 Atk, 252 in Speed, HP or some Satk, in your preference
