Counter that Pokémon!

Magnezone @Choice Specs
Ability: Magnet Pull
EVs: 4 Def / 252 Sp. Atk / 252 Spe
-Volt Switch
-Thunderbolt
-Flash Cannon
-Hidden Power Fire

At best you can 3HKO including the damage on the switch whilst Magnezone can outspeed for a guaranteed 2HKO and a possible OHKO.

 

[Frozocrone]

Finally time for my favourite Gen 7 to shine!

Turtonator @ Assault Vest
Ability: Shell Armour
Modest Nature
EVs: 248 HP / 76 Def / 4 SpA / 176 SpD
-Overheat
-Dragon Pulse
-Flash Cannon
-Focus Blast

Magnezone musters a 4HKO at best with Thunderbolt. Overheat OHKO's.

 

[Nah]

Too bad it loses to my favorite Gen 7 Pokemon:

Toxapex @ Black Sludge
Ability: Regenerator
EVs: 248 HP / 184 Def / 76 SpD
Calm Nature
-Scald
-Recover
-Haze
-Toxic

While Scald does little damage, Turtonator doesn't do a lot either, and since Toxapex has recovery while Turt doesn't, it'll easily outlast it and the turtle will eventually succumb to chip damage from Scald+Toxic.

Sigilyph @Life Orb
Ability: Magic Guard
EVs: 4 HP / 252 Sp. Atk / 252 Spe
Timid Nature
-Psyshock
-Heat Wave
-Roost
-Energy Ball

Toxapex's Scald can 4HKO at best and is more likely to 5HKO without Sigilyph having to fear a burn from it. Toxic is similarly useless. Meanwhile, Sigilyph can 2HKO with Psyshock and Roost away any damage.

Grimer-Alola @ Eviolite
Ability: Poison Touch
EVs: 252 HP / 4 Atk / 252 SpD
Careful Nature
- Knock Off
- Crunch
- Toxic
- Taunt

Sigilyph has about a 50% chance to 4HKO my Grimer-A w/ LO. Assuming LO is knocked off right after you come in, it's definitely a 5HKO. Knock Off+Crunch is an easy 2HKO and taunt is there just to prevent the roosting damage off.

Cobalion @ Leftovers
Ability: Justified
EVs: 4hp/252atk/252spe
Jolly nature
-Close Combat
-Iron Head
-Swords Dance
-Stone Edge

Poor Grimer never stood a chance as an unboosted Close Combat has a chance to 2HKO. Grimer's Dark-type moves will only make it stronger and Knock Off + Crunch still do low damage despite Close Combat's defense drops.

 

[gimmepie]

Togekiss @Leftovers
Ability: Serene Grace
EVs: 252 HP / 252 Def / 4 Sp. Atk
Bold Nature
-Air slash
-Dazzling Gleam
-Roost
-Nasty Plot

Ice Punch is nasty to switch into, but can only 2HKO at best with about a 40% chance to be a 3HKO instead whilst the rest of your moves can barely scratch Togekiss. Togekiss however can switch in, OHKO with Air Slash and then heal any damage it took with Roost.

 

[Frozocrone]

Raikou @ Assault Vest
Ability: Pressure
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Thunderbolt
- Volt Switch
- Hidden Power Ice
- Shadow Ball

Togekiss can only 3HKO at +2 with Dazzling Gleam. Raikou can switch in and outspeed for the 2HKO with Thunderbolt.

 

[gimmepie]

Lanturn @Leftovers
Ability: Volt Absorb
EVs: 104 HP / 192 Def / 212 Sp. Def
Calm Nature
-Scald
-Volt Switch
-Toxic
-Heal Bell

Raikou pretty much can't scratch Lanturn and whilst Lanturn can't do much damage back, Toxic will allow it to cripple Raikou and outlast it if it doesn't switch out.

 

[Frozocrone]

Oh look, she returns:

Clefable @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 172 Def / 84 SpD
Calm Nature
- Calm Mind
- Moonblast
- Soft-Boiled
- Flamethrower

CleSLAYble sets up and beats Lanturn with ease (Moonblast is a 2HKO at +3, possible OHKO at +6). Toxic does nothing.

 

[Dark Azelf]

Pyukumuku @ Leftovers
Ability: Unaware
EVs: 248 HP / 164 Def / 96 SpD
Bold Nature
- Toxic
- Recover
- Soak
- Gastro Acid

Op. No weaks.

Barboach @ Eviolite
Ability: Anticipation
EVs: 248 HP / 8 Atk / 252 SpD
Sassy Nature
- Earthquake
- Waterfall
- Amnesia
- Rest

First off, Barboach has Anticipation just to scout for the HP Grass of course.

Flash Cannon and HP Ice can 4HKO at the best, bar a crit. Just in case, Barboach packs Amnesia and Rest to boost and out last Zone.

EQ is an easy 2HKO.

 

[gimmepie]

Mostly I just wonder why you didn't use Whiscash.

Tropius @Sitrus Berry
Ability: Harvest
EVs: 248 HP / 252 Def / 8 Sp. Def
Bold Nature
-Giga Drain
-Leech Seed
-Substitute
-Air Slash

Tropius 2HKOs and heals off off Giga Drain and can easily set up Substitute whilst Barboach can't touch Tropius at all really.

 

[Nah]

everyone wants to be cute after I posted Arbok I guess

Froslass @ Focus Sash
Ability: Cursed Body
EVs: 252 SpA / 252 Spe / 4 HP
Timid Nature
-Ice Beam
-Will-o-Wisp
-Hex
-Hidden Power Fire

ded

Magcargo @Leftovers
Ability: Flame Body
EVs: 248 HP / 8 Def / 252 Sp. Def
Calm Nature
-Lava Plume
-Stealth Rock
-Toxic
-Recover

I dunno, it's more fun to use counters that you wouldn't be caught dead with in an actual battle. Anyway, that Froslass can't do anything to Magcargo unless you count a potential 6HKO from Hex but is 2HKOd itself by Lava Plume and allows for an easy setting of Stealth Rock.

 

[Frozocrone]

Luvdisc @ Focus Sash
Ability: Swift Swim
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Hydro Pump
- Ice Beam
- Rain Dance
- Safeguard

Yeah it's sad when your counter is a Luvdisc that OHKO's with Hydro Pump :)

 

[gimmepie]

Vaporeon @Leftovers
Ability: Water Absorb
EVs: 204 HP / 248 Def / 56 Sp. Def
Calm Nature
-Wish
-Protect
-Toxic
-Scald

Even if you use Safeguard to protect from Toxic, you can't touch Vaporeon really and will eventually die to Scald.

 

[Pepperton]

Breloom @ Toxic Orb
Ability: Poison Heal
EVs: 12 HP / 244 Atk / 252 Spe
Jolly Nature
- Swords Dance
- Superpower
- Seed Bomb
- Facade

i guess this is boring but it does hard counter

 

[HardstyleRaver2]

Altaria @ Altarianite
Ability: Cloud Nine
EVs: 252 HP / 136 Def / 92 SpD / 28 Spe
Impish Nature
- Dragon Dance
- Roost
- Return
- Heal Bell

0 Atk Pixilate Altaria-Mega Return vs. 12 HP / 0 Def Breloom: 342-404 (129.5 - 153%) -- guaranteed OHKO
