Aggron can simply spam EQ for the 3HKO, while Reli's EQ does jack shit.

Hopefully one post will bring this back to life.

Aerodactyl @ Life Orb
Nature - Adamant
Ability - Unnerve
EV's - 212 Atk / 44 Def / 252 Spe
- Stone Edge
- Eathquake
- Ice Fang
- Aerial Ace

252+ SpA Volcarona Giga Drain vs. 0 HP / 0 SpD Aerodactyl: 118-139 (39.2 - 46.1%) -- guaranteed 3HKO
252+ SpA Volcarona Fiery Dance vs. 0 HP / 0 SpD Aerodactyl: 93-111 (30.8 - 36.8%) -- 71.9% chance to 3HKO

212+ Atk Life Orb Aerodactyl Stone Edge vs. 96 HP / 0 Def Volcarona: 1097-1300 (327.4 - 388%) -- guaranteed OHKO

Rhyperior @ Leftovers
Ability: Solid Rock
EVs: 212 HP / 44 Atk / 252 Def
Adamant Nature
- Earthquake
- Stone Edge
- Ice Punch
- Fire Punch

212+ Atk Life Orb Aerodactyl Earthquake vs. 212 HP / 252 Def Solid Rock Rhyperior: 129-152 (30.4 - 35.8%) -- guaranteed 4HKO after Leftovers recovery

Hippowdon @ Leftovers
Ability: Sand Stream
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature

- Earthquake
- Whirlwind
- Stone Edge
- Slack Off

Rhyperior can't 3HKO this thing and Hippo can just Slack Off the damage anyway. Meanwhile Hippo can beat it with repeated EQs or use Whirlwind.

@ Leftovers
Ability: Regenerator
EVs: 248hp/252def/8spd
IVs: 30atk/30spa/30spe
Bold Nature (+Def, -Atk)
- Giga Drain
- Sleep Powder
- Hidden Power [Fire]
- Leech Seed

Hard countered basically, even with Stone Edge's crit chance (I'm factoring that in due its better chance of landing one) Hippo only 6hko's, normal hits are 8hko's. Tangrowth can safely come in, put it to sleep, set up a Leech Seed and/or 2hko with Giga Drain.

 

[Nah]

-Magmortar w/Life Orb
Nature: Mild
Ability: Vital Spirit
EVs: 252 Sp.Attack, 252 Speed, 4 Attack
Moves: Fire Blast, Thunderbolt, Earthquake, Hidden Power Grass

Giga Drain and HP Fire do pitiful damage to Magmortar, and Vital Spirit prevents it from being put to sleep by Sleep Powder. Fire Blast hits Tangrowth like an artillery blast.

Zweilous @ Eviolite
Ability: Hustle
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Crunch
- Dragon Tail
- Rest
- Sleep Talk

4 Atk Life Orb Magmortar Earthquake vs. 252 HP / 0 Def Eviolite Zweilous: 81-96 (23.2 - 27.5%) -- 72.6% chance to 4HKO

0 Atk Hustle Zweilous Crunch vs. 0 HP / 0- Def Magmortar: 174-205 (59.7 - 70.4%) -- guaranteed 2HKO

Behold the birthday cake:

Slurpuff @ Sitrus Berry
Nature - Adamant
Ability - Unburden
EV's - 4 HP / 252 Atk / 252 Spe
- Belly Drum
- Play Rough
- Return
- Substitute

Can come in and set up a substitute or start off with a Belly Drum right away. I know it doesn't matter but an Unburden +6 Slurpuff is scary.

4 Atk Hustle Zweilous Crunch vs. 52 HP / 0 Def Slurpuff: 64-76 (20.1 - 23.8%) -- guaranteed 5HKO
Zweilous Dragon Tail vs. Slurpuff: 0-0 (0 - 0%) -- aim for the horn next time

+6 252+ Atk Slurpuff Play Rough vs. 252 HP / 0 Def Eviolite Zweilous: 1660-1960 (477 - 563.2%) -- guaranteed OHKO

 

[Nah]

Mega Scizor @Scizorite
Ability: Technician
Impish Nature
EVs: 252 HP/252 Def/4 Atk
-Bullet Punch
-U-Turn
-Swords Dance
-Knock Off

This is basically the best that can be done for switching into a +6 Slurpuff:

+6 252+ Atk Slurpuff Drain Punch vs. 252 HP / 252+ Def Mega Scizor: 147-174 (42.7 - 50.5%) -- 2.3% chance to 2HKO

4 Atk Technician Mega Scizor Bullet Punch vs. 4 HP / 0 Def Slurpuff: 210-248 (68.6 - 81%) -- guaranteed 2HKO

And honestly Slurpuff's chance to 2HKO is so low that we'll call that good enough. It's probably not getting back enough HP from Drain Punch to survive 2 Bullet Punches anyway (though since it's likely to be at 75% HP it could be OHKO'd if the rolls go in Scizor's favor).

Arcanine @ Helix Fossil
Ability: Intimidate
EVs: 252 HP / 252 Def / 4 SpA
Bold Nature
- Overheat
- Morning Sun
- Solar Beam
- Sunny Day

Switches in, setting Scizor's attack back by one. Neither setting up swords dance nor attacking right away allows it to even 2 hit Ko Arcanine, letting the dog launch an overheat to knock it out.
+1 4 Atk Mega Scizor Knock Off vs. 252 HP / 252 Def Arcanine: 136-160 (35.4 - 41.6%) -- guaranteed 3HKO

4 SpA Helix Fossil Arcanine Overheat vs. 252 HP / 0 SpD Mega Scizor: 564-664 (163.9 - 193%) -- guaranteed OHKO

 

[srinator]

helix fossil? what?

Altaria @ Altarianite
Ability: Cloud Nine
Happiness: 0
EVs: 248 HP / 8 Atk / 252 SpD
Careful Nature
- Cotton Guard
- Roost
- Frustration
- Dragon Dance

4 SpA Arcanine Overheat vs. 248 HP / 252+ SpD Mega Altaria: 49-58 (13.8 - 16.4%) -- possible 7HKO
k
4 SpA Arcanine Solar Beam vs. 248 HP / 252+ SpD Mega Altaria: 30-36 (8.4 - 10.1%) -- possibly the worst move ever

Heatran @ Leftovers
Ability: Flash Fire
EVs: 248 HP / 192 Def / 68 Spe
Bold Nature
- Lava Plume
- Toxic
- Taunt
- Protect

Yay for physically defensive Heatran

 

[Somewhere_]

I dont play OU much, but...

Garchomp @ LO
Ability: rough skin
Fire fang
EQ
Dragon claw
SD

 

[2Fruit]

I'll just assume the normal max attack and speed with jolly.


Togekiss @ Choice Scarf
Ability: Serene Grace
EVs: 148 HP / 252 SpA / 108 Spe
Modest Nature
- Dazzling Gleam
- Trick
- Air Slash
- Soft-Boiled

If Garchomp uses swords dance when Togekiss switches in, I'm pretty sure Togekiss can trick it's choice scarf onto the chomp to force it to keep using SD. But even if it can't, Togekiss still wins.

Togekiss is immune to earthquake and dragon claw, forcing Chomp to use fire fang, which is a 3-4HKO at +0 and 2HKO at +1. Togekiss has minimum speed to go before max speed garchomp with choice scarf and enough power to 2hko, and occasionally 1hko's it, further increased in likelyhood by the fact that chomp uses life orb.

252+ SpA Togekiss Dazzling Gleam vs. 4 HP / 0 SpD Garchomp: 312-368 (87.1 - 102.7%) -- 18.8% chance to OHKO

252 Atk Life Orb Garchomp Fire Fang vs. 148 HP / 0 Def Togekiss: 96-114 (27.5 - 32.7%) -- guaranteed 4HKO

 

[Totally not a cat]

Manectric @Manectricite
136 HP / 252 SpDef/ 120 Speed
Calm nature

-Thunderbolt
-Literally whatever for the rest three moves

Worst case scenario it'll eat a Dazzling Gleam in the switch in and lose 50%
252+ SpA Togekiss Dazzling Gleam vs. 136 HP / 252+ SpD Manectric: 135-159 (42.8 - 50.4%) -- 1.2% chance to 2HKO

Next turn it mega evolves and takes some more damage because it's mega speed hasn't taken effect yet, attacks with T-bolt
252+ SpA Togekiss Dazzling Gleam vs. 136 HP / 252+ SpD Mega Manectric: 114-135 (36.1 - 42.8%) -- guaranteed 3HKO
0 SpA Mega Manectric Thunderbolt vs. 248 HP / 0 SpD Togekiss: 222-264 (59.5 - 70.7%) -- guaranteed 2HKO after Leftovers recovery

Next turn Mega Manetric kills it with T-bolt because it hits 336 with 120 EVs, whereas Togekiss sits at 334 after the scarf with 108 EVs.

If it were to switch into Air slash, it might flinch on the second turn due to Serene Grace, but Manectric can eat those all day long so it's no problem because from that turn on it will be faster and flinching will be a non issue. If Togekiss gets trapped into Trick or Softboiled it's as good as gone already.
