[Omicron]

Hariyama @ Flame Orb
Ability: Guts
EVs: 252 HP / 252 Def / 4 Atk
Brave Nature
- Fake Out
- Close Combat
- Knock Off
- Ice Punch

4+ Atk Guts Hariyama Close Combat vs. 0 HP / 0- Def Kyurem-B: 554-654 (141.6 - 167.2%) -- guaranteed OHKO

Kyurem-b can't OHKO.

 

[KorpiklaaniVodka]

Still can't switch into Outrage.

Quagsire @ Leftovers
Trait: Unaware
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature

- Stockpile
- Waterfall
- Earthquake
- Recover

Doesn't really care about Close Combat, can boost its defenses, and wear Hariyama down with repeated Earthquakes.

 

[Omicron]

Carnivine @ Leftovers
Trait: Levitate
EVs: 252 HP / 4 Atk / 252 Sp. Def
Careful Nature

- Knock Off
- Power Whip
- Sludge Bomb
- Stockpile

4 Atk Carnivine Power Whip vs. 252 HP / 252+ Def Quagsire: 412-492 (104.5 - 124.8%) -- guaranteed OHKO

Immune to earthquake and waterfall is probably the worst move ever.

 

[Nah]

Magmortar w/Choice Scarf
Nature: Modest
Ability: Vital Spirit
EVs: 252 Sp.Attack, 252 Speed, 4 HP
Moves: Fire Blast, Thunderbolt, Focus Blast, Hidden Power Grass

4 Atk Carnivine Knock Off (97.5 BP) vs. 4 HP / 0 Def Magmortar: 97-115 (33.2 - 39.3%) -- 100% chance to 3HKO
That's Carnivine's best option.

Fire Blast OHKOs.

 

[Dark Azelf]

Tyranitar@Choice Band
176 HP / 252 Atk / 80 Speed
Adamant Nature
Trait: Sandstream
- Stone Edge
- Crunch

[Omicron]

Lucario @ Life Orb
Ability: Justified
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Close Combat
- Swords Dance
- Extreme Speed
- Crunch

252+ Atk Life Orb Lucario Close Combat vs. 176 HP / 0 Def Tyranitar: 920-1081 (238.9 - 280.7%) -- guaranteed OHKO

Yeah, forgot about Fire Punch. It is indeed not a counter.

 

[PlatinumDude]

Lucario @ Life Orb
Ability: Justified
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Close Combat
- Swords Dance
- Extreme Speed
- Crunch

252+ Atk Life Orb Lucario Close Combat vs. 176 HP / 0 Def Tyranitar: 920-1081 (238.9 - 280.7%) -- guaranteed OHKO

Not a counter because it can't switch into Fire Punch or Superpower.

Anyway:

Spiritomb:

-Foul Play
-Will-o-Wisp
-Rest
-Sleep Talk
Nature: Bold
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Infiltrator

The best Lucario can do to Spiritomb is Crunch, which Spiritomb tanks.

 

[Nah]

Scizor w/Leftovers
Nature: Adamant
Ability: Technician
EVs: 252 Attack, 252 Speed, 4 Sp.Defense
Moves: Swords Dance, Bullet Punch, Knock Off, Superpower

Can survive all of Mega Diancie's attacks at +1:

176 Atk Diancie Diamond Storm vs. 0 HP / 0 Def Scizor: 183-216 (65.1 - 76.8%) -- guaranteed 2HKO
+1 176 SpA Diancie Earth Power vs. 0 HP / 4 SpD Scizor: 197-232 (70.1 - 82.5%) -- guaranteed 2HKO
+1 176 SpA Diancie Moonblast vs. 0 HP / 4 SpD Scizor: 156-183 (55.5 - 65.1%) -- guaranteed 2HKO


Bullet Punch cleanly OHKOs.

Hidden Power Fire's a nice move for Mega Diancie

 

[DarkIllumination]

Slowbro
nature: Relaxed
Item: slowbronite
ability: regenerator/Shell armor after ME
moves: slackoff, scald, fireblast, icebeam
Evs: 252 hp, 252 def, 4 spattk
Mega slowbro avoids critical hits with shell armor and with enormous defense it lives any move with slackoff, can burn Scizor with scald, OK with fireblast, and does not care about bullet punch, super power is resisted, knock off does a 1/3 at most, and can OK before it can set up enough swords dances for Mega Slowbro to care.

Mega Blastoise @ Blastoisinite
Ability: Torrent -> Mega Launcher
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
- Hydro Pump

Swampert @ Leftovers
Trait: Torrent
EVs: 240hp/16atk/252spd
Sassy nature (+Sp. Def, -Spe)
-Stealth Rock
-Scald
-Earthquake
-Roar

252 SpA Choice Specs Raikou Extrasensory vs. 240 HP / 252+ SpD Swampert: 93-110 (23.1 - 27.4%) -- possible 5HKO after Leftovers recovery

16 Atk Swampert Earthquake vs. 32 HP / 0 Def Raikou: 306-360 (93 - 109.4%) -- 56.3% chance to OHKO

 

[Nah]

-Serperior w/Life Orb

EVs: 252 Sp.Attack, 252 Speed, 4 HP
Moves: Leaf Storm, Giga Drain, Hidden Power Fire, Dragon Pulse

 

[Detox]

Skarmory @ Leftovers
Ability: Sturdy
EVs: 252 HP / 252 Def / 4 SpD
Impish Nature
- Roost
- Whirlwind
- Brave Bird
- Defog

A pretty cliché counter, but Skarmory gets the job done. Bouffalant's best option against it is a possible 7HKO, but even then it fails to do much of anything to Skarmory when you factor in Roost. Skarmory can dispatch Bouffalant with Brave Bird in four turns, though if it Roosts off the Brave Bird recoil in the process it may fall to a 5HKO.

252+ Atk Bouffalant Stone Edge vs. 252 HP / 252+ Def Skarmory: 61-72 (18.2 - 21.5%) -- possible 7HKO after Leftovers recovery

0 Atk Skarmory Brave Bird vs. 172 HP / 0 Def Bouffalant: 112-133 (29.9 - 35.5%) -- guaranteed 4HKO after Leftovers recovery

252+ SpA Choice Specs Magnezone Flash Cannon vs. 248 HP / 0 SpD Krookodile: 288-340 (73.2 - 86.5%) -- guaranteed 2HKO after Leftovers recovery

Outspeeds and then Earthquakes.

 

[Registration]

Sceptile
252+ sp attack 252 speed
giga drains, outspeeds and can come in on the earthquake.

Landorus-Therian @ Leftovers
Ability: Intimidate
EVs: 252 HP / 240 Def / 8 SpD / 8 Spe
Impish Nature
- Stealth Rock
- Earthquake
- U-turn
- Stone Edge

-1 252 Atk Life Orb Mold Breaker Excadrill Iron Head vs. 252 HP / 240+ Def Landorus-T: 91-109 (23.8 - 28.5%) -- possible 5HKO after Leftovers recovery
-1 252 Atk Life Orb Mold Breaker Excadrill Rock Slide vs. 252 HP / 240+ Def Landorus-T: 58-69 (15.1 - 18%) -- possible 8HKO after Leftovers recovery

@ Chesto Berry
Trait: Pressure
EVs: 252hp/252def/4spa
Bold Nature (+Def, -Atk)
-Rest
-Calm Mind
-Scald
-Ice Beam

Was going to use standard CroCune but I felt this set works a bit better in case Sleep Talk doesn't go on Scald.

If Lando gets a free turn to set up Rocks:
0 Atk Landorus-T Earthquake vs. 252 HP / 252+ Def Suicune: 97-115 (24 - 28.4%) -- guaranteed 4HKO after Stealth Rock

If it doesn't:
0 Atk Landorus-T Earthquake vs. 252 HP / 252+ Def Suicune: 97-115 (24 - 28.4%) -- 96.9% chance to 4HKO

Ice Beam's a 2HKO:
4 SpA Suicune Ice Beam vs. 252 HP / 8 SpD Landorus-T: 284-336 (74.3 - 87.9%) -- guaranteed 2HKO after Leftovers recovery

Another scenerio is Lando uses the second Earthquake (assuming Suicune switched into the first one), Suicune sets up a Calm Mind, goes for the third and Suicune can either Rest or just finish it off with an Ice Beam:
+1 4 SpA Suicune Ice Beam vs. 252 HP / 8 SpD Landorus-T: 428-504 (112 - 131.9%) -- guaranteed OHKO

 

[Nah]
