I wanted to give the famed DeoSharp a go around using Rain as a back-drop and utilizing a Dragon-Steel-Fairy core. Possible changes are tossing in LO Keldeo for raw power or Omastar as a check to Talonflame.

Timid:Drizzle
4 HP|252 Sp.Atk|252 Speed
~Hydro Pump
~Focus Blast
~Ice Beam
~Sleep Talk
Works great against BP Smeargle leads, Spore? no-no, not today. Absorbs sleep and keep on trucking.
Deoxys-S@Damp Rock
Bold:Pressure
EVs need work, enough speed to beat Adamant Sand Rush Excadrill
~Psycho Boost/Super Power
~Stealth Rock
~Rain Dance
~Taunt
I lead with Deoxys more often than not, and if the team is weak to Rocks then I make a point to set them up. Superpower dispatches Tyranitar quite handily.
Kyurem-B@Leftovers
Naughty:Teravolt
56 HP|80 Atk|132 Sp.atk|240 Speed
~Ice Beam
~Fusion Bolt
~Substitute
~Outrage
56 HP Evs gives me 101 Subs, which is lovely when you consider that MScizor's Bullet Punch still leaves me in Sub range. here are some relevant clacs.
76+ Atk Teravolt Kyurem-B Outrage vs. 252 HP / 0 Def Rotom-W: 223-264 (73.3 - 86.8%) -- guaranteed 2HKO after Stealth Rock and Leftovers. recovery.
76+ Atk Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Togekiss: 276-326 (73.7 - 87.1%) -- 87.5% chance to OHKO after Stealth Rock.
76+ Atk Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Azumarill: 318-376 (78.7 - 93%) -- 37.5% chance to OHKO after Stealth Rock. Even though most Azumarill only run around 164 HP, in order to out-speed Jellicent.
76+ Atk Teravolt Kyurem-B Fusion Bolt vs. 4 HP / 0 Def Talonflame: 350-412 (117.4 - 138.2%) -- guaranteed OHKO. Though no one in their right mind would switch anything into CB Talonflame unless it resists. Though non-boosted SB Brave Bird does a little over 50%.
76+ Atk Teravolt Kyurem-B Outrage vs. 4 HP / 0 Def Mega Gengar: 286-337 (109.1 - 128.6%) -- guaranteed OHKO. While 3 attacks Gengar relies on Focus Miss for the OHKO, or Dazzling Gleam to 2HKO.
138 SpA Teravolt Kyurem-B Ice Beam vs. 4 HP / 0 SpD Dragonite: 508-604 (156.7 - 186.4%) -- guaranteed OHKO. Teravolt plows through WeakNite.
Now for defensive stars.
138 SpA Teravolt Kyurem-B Ice Beam vs. 252 HP / 0 SpD Skarmory: 171-202 (51.1 - 60.4%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
138 SpA Teravolt Kyurem-B Ice Beam vs. 252 HP / 0 SpD Gourgeist-Super: 324-384 (86.6 - 102.6%) -- 93.8% chance to OHKO after Stealth Rock
138 SpA Teravolt Kyurem-B Ice Beam vs. 252 HP / 4 SpD Mega Venusaur: 218-258 (59.8 - 70.8%) -- guaranteed 2HKO after Stealth Rock. In return Giga Drain does a paltry ~20%, and if you're behind a Sub, it can't touch you with Sleep Powder or Leech Seed.
76+ Atk Teravolt Kyurem-B Outrage vs. 252 HP / 0 Def Trevenant: 297-351 (79.4 - 93.8%) -- 43.8% chance to OHKO after Stealth Rock. Subbing first blocks ALL of the ghost-tree's moves, barring Phantom Force which you can predict around anyway.
76+ Atk Teravolt Kyurem-B Outrage vs. 252 HP / 0 Def Celebi: 237-280 (58.6 - 69.3%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery. Not that you will see it much, it needs Psychic to break the Sub, and it's other moves are blocked by the Sub.
76+ Atk Teravolt Kyurem-B Outrage vs. 252 HP / 252+ Def Blissey: 430-507 (60.2 - 71%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
76+ Atk Teravolt Kyurem-B Outrage vs. 252 HP / 252+ Def Eviolite Chansey: 313-370 (44.4 - 52.5%) -- guaranteed 2HKO after Stealth Rock. God forbid the Eviolite was knocked off earlier in the match.
Azumarril@Choice Band
Adamant:Huge Power
92 HP|252 Attack|164 Speed
~Aqua Jet
~Play Rough
~Superpower
~Waterfall
The advent of the fairy type brought me a new toy to use in place of Kabutops. Who needs Swift Swim when you have priority? Adamant, CBanded, Rain-boosted Aqua Jet smashes things! if you don't resist then may God have mercy on your soul. 164 Speed allows me to barely outrun Scizor and hit it with a boosted STAB Aqua JEt before it hits me with Bullet Punch before it can burn me. Gonna try to switch in a steel type to absorb the blow?
252+ Atk Choice Band Huge Power Azumarill Waterfall vs. 252 HP / 0 Def Scizor in Rain: 358-423 (104 - 122.9%) -- guaranteed OHKO
252+ Atk Choice Band Huge Power Azumarill Waterfall vs. 252 HP / 0 Def Mega Scizor in Rain: 268-316 (77.9 - 91.8%) -- 31.3% chance to OHKO after Stealth Rock
252+ Atk Choice Band Huge Power Azumarill Waterfall vs. 252 HP / 0 Def Mega Aggron in Rain: 170-201 (49.7 - 58.7%) And MAggron is one of the premiere physical tanks in OU/minus the crippling lack of recovery.
Zapdos@Leftovers
Bold:Pressure
248 HP|168 Def|68 Sp.Atk|20 Speed
~Volt Switch
~Defog
~Roost
~Heat Wave
I have come to like the utility Zapdos brings to the table. Volt Switch for momentum and nabs the OHKO on Talonflame 25% of the time with no prior damage. Guaranteed with Stealth Rock.
64 Sp.Atk Zapdos Volt Switch vs. 4 HP / 0 SpD Talonflame: 264-312 (88.5 - 104.6%) -- 25% chance to OHKO
Bisharp@Life Orb/Assault Vest
Adamant:Defiant
252 Hp|252 Attack| 4 Def
~Sucker Punch
~Knock Off
~Iron Head
~Sword's Dance/Brick Break/Pursuit
Bisharp received a huge, indirect buff in the form of defog, giving Bisharp a major niche as an anti-defog measure. Its ability, Defiant, gives it a free SD every time it comes in on Defog, which makes Bisharp a huge threat. Furthermore, with the steel nerf and Knock Off buff, Bisharp has one of the most spammable moves in the game at its disposal, plus powerful priority in Sucker Punch.
All thoughts are welcome!
