Counter that Pokémon

[Jin Of The Gale]

Politoed (F) @ Choice Specs
Trait: Drizzle
EVs: 4 Def / 252 SAtk / 252 SDef
Calm Nature (+SDef, -Atk)
- Surf
- Ice Beam
- Focus Blast
- Hidden Power [Grass]

252+ SpA Mega Charizard Y Focus Blast vs. 0 HP / 252+ SpD Politoed: 120-142 (37.3 - 44.2%) -- guaranteed 3HKO
252+ SpA Mega Charizard Y Solar Beam vs. 0 HP / 252+ SpD Politoed: 240-284 (74.7 - 88.4%) -- guaranteed 2HKO

If Charizard uses Solar Beam on the turn Politoed switches in, it won't be able to attack due to Drizzle. On the next turn, Politoed survives Solar Beam and OHKOs with Surf.

 

[KorpiklaaniVodka]

Amoonguss @ Leftovers
Trait: Regenerator
EVs: 252 HP / 20 SpA / 236 SpD
Calm Nature

- Giga Drain
- Spore
- Leech Seed
- Protect / Hidden Power Ice

252 SpA Choice Specs Politoed Ice Beam vs. 252 HP / 236+ SpD Amoonguss: 192-228 (44.4 - 52.7%) -- guaranteed 3HKO after Leftovers recovery

As you can see, Calm Specs Politoed cannot 2HKO specially defensive Amoonguss with Ice Beam, thanks to Leftovers. Amoonguss can then put the frog to sleep and eventually 3HKO it with Giga Drain (20 SpA Amoonguss Giga Drain vs. 0 HP / 252+ SpD Politoed: 104-126 (32.3 - 39.2%) -- 99% chance to 3HKO). Also, if Politoed is lucky and manages to wake up, Amoonguss can easily switch out and recover 33% of its health thanks to Regenerator. The mushroom can also use Leech Seed to help recover health faster, while Protect allows it to scout for any switch. HP Ice can be used over Protect to catch a dragon on the switch (especially Dragonite, a common partner to Politoed, who is 2HKOed after Stealth Rock damage).

Magmortar @ Life Orb
Ability: Vital Spirit
EVs: 4 Def / 252 SAtk / 252 Spd
Modest Nature
- Fire Blast
- Thunderbolt
- Focus Blast
- Hidden Power Grass​

Magmortar is immune to Spore thanks to Vital Spirit. Everything else is self-explanatory!

 

[PlatinumDude]

Dragalge:

-Toxic Spikes
-Sludge Bomb
-Dragon Tail/Dragon Pulse
-Surf/Thunderbolt
Nature: Sassy/Calm
EVs: 252 HP/40 Def/216 SDef
Item: Black Sludge

Yes, I'm aware that Dragalge isn't that good with Adaptability unavailable, but at least it walls the entirety of Magmortar's set and uses it as setup bait for Toxic Spikes. Dragalge also hits Magmortar hard with Surf if it has it.

 

[halcyonic]

Mawile @ Mawilite
Intimidate > Huge Power
132 HP / 252 Atk / 124 SpD
Adamant
-Swords Dance
-Play Rough
-Sucker Punch
-Iron Head

Dragalge Surf vs. 132 HP / 124 SpD Mega Mawile: 58-69 (21.1 - 25.1%)
Dragalge Thunderbolt vs. 132 HP / 124 SpD Mega Mawile: 58-69 (21.1 - 25.1%)

Mawile will have no trouble setting up and OHKO'ing in return.

 

[Nah]

It doesn't normally run a set like this, but:
-Mega Aggron w/Aggronite
Nature: Impish
Ability: Sturdy----->Filter
EVs: 252 HP, 252 Defense, 4 Attack
Moves: Iron Head, Earthquake, Thunder Wave, Stealth Rock

Unless I'm overestimating its defense capabilities, Mega Aggron should be able to take a +2 Sucker Punch from Mega Mawile and OHKO back with Earthquake. Shouldn't take much damage from Play Rough or Iron Head.

 

[TrainerNico]

Torkoal@White Herb
Nature:Bold
Ability:Shell Armor
252 HP / 132 Def / 128 SpA
-Overheat
-Yawn
-Rapid Spin
-Hidden Power Grass

Mega Aggron 4 Atk Iron Head vs 252 HP / 132 Def Torkoal: 36-42 HP Damage(10.47%-12.21%)

Mega Aggron 4 Atk Earthquake vs 252 HP / 132 Def Torkoal: 120-142 HP Damage(34.88%-41.28%)

Torkoal can take the hits, then retaliate back with Overheat to 2HKO.

Edit:My bad

 

[Zeffy]

Suicune @Leftovers
Trait: Pressure
EVs: 252 HP / 252 Def / 4 SDef
Bold nature (+Def, -Atk)
- Rest
- Sleep Talk
- Calm Mind
- Scald / Surf

crocune procune B)

Anyway, HP Grass fails to do any significant damage whilst Suicune can just keep boosting and Rest off the damage or 2hko with either Scald or Surf. Yawn also isn't much of a problem with Sleep Talk.

 

[Nah]

-Lanturn w/Magnet
Ability: Water Absorb
Nature: Modest
EVs: 252 HP, 252 Sp.Attack, 4 Speed
Moves: Charge, Thunderbolt, Ice Beam, Discharge/Scald

Lanturn is immune to Suicune's only attack, Surf/Scald. Can use Charge (lol Charge is getting use) to boost its power to +6, winning the boosting war because of the super-effective STAB and Suicune having no Sp.Defense EVs.

 

[Zeffy]

uhmmm alright XD a bit overcreative though haha

Mamoswine @Life Orb
Trait: Thick Fat
EVs: 252 Atk / 4 Def / 4 Spd
Adamant nature (+Atk, -SAtk)
- Icicle Crash
- Ice Shard
- Earthquake
- Superpower

should be wary of scald when switching in since it can 2hko. Mamo can outspeed and ohko with earthquake though soooo

 

[halcyonic]

Rotom-W @ Lefties
Levitate
252 HP / 252 Def / 4 SpA
Bold nature
- Hydro Pump
- Volt Switch
- Will-O-Wisp
- Pain Split

252+ Atk Life Orb Mamoswine Superpower vs. 252 HP / 252+ Def Rotom-W: 129-152 (42.4 - 50%) -- guaranteed 3HKO after Leftovers recovery

-1 252+ Atk Life Orb Mamoswine Superpower vs. 252 HP / 252+ Def Rotom-W: 86-101 (28.2 - 33.2%) -- 89.6% chance to 4HKO after Leftovers recovery

Rotom-W can choose to use Pain Split to gain back some HP or it could use Will-O-Wisp to cripple it first. If not, just outspeed and go for the KO q:

 

[Aeroblast]

The guy didn't say if Venusaur was holding onto a Venusaurite or not, so I was kind of confused. xD" Anyway…

I was unsure if mega stones were allowed so I just kind of left it alone, my bad.

Anyways to the above

Gastrodon @ Leftovers
252 HP/252 Def/6 SpD
Relaxed nature
Earthquake
Scald
Toxic
Recover

Gastrodon can easily outstall Rotom W with recover and toxic and is immune to both STABs. Pain split is unreliable.

 

[Opposite Day]

Time to switch this up - I'm not bothered about what COUNTERS a flipping Gastrodon, I'd rather lure it to stay in so I can get rid of it :>

Thundurus-T @ Expert Belt
4 Att / 252 SpA / 252 Spe
Hasty Nature
- Thunderbolt
- Grass Knot
- Superpower
- U-Turn

Mixed wallbreaking Thundy-T switches in for "free" on 3/4ths of Gastrodon's moveset, and while it takes 32.4 - 38.4% from an uninvested Scald (which is pretty bad to be honest) it has the benefit of being perceived as a pokemon that Gastrodon can usually wall (and such if you have played "badly" beforehand it adds to the illusion, catching your opponent off guard), letting you get a surprise KO with an ebelt boosted Grass Knot (95.7 - 112.6%). Should be plenty if Gastrodon has taken any prior damage at all / got burned by Rotom-W, or alternatively if you do not want to bluff a choiced item, run LO and do (103.7 - 122%).


ALSO: I'm pretty certain Suicune could outstall Lanturn by not choosing Sleep Talk half of the time when it is resting. Charge only boosts the electric attack by +2 at any given point iirc (and gives a +1 to SpD every time it is used)
so it would go like this:

Spoiler:

Turn 1: Suicune uses Calm Mind (+1), Lanturn switches in.

Turn 2: Suicune uses Calm Mind (+2) (it is faster after all) - Lanturn uses either Charge or Thunderbolt - TBolt does (27.2 - 32.6%) to a +2 Cune -- 55.5% chance to 4HKO after Leftovers recovery

Turn 3: Suicune uses Calm Mind (+3) - Lanturn either uses +2 TBolt or Charges. - +2 Tbolt does (43.5 - 51.9%). You now have to Charge again to give TBolt +2.

Turn 4: Suicune uses Calm Mind (+4) - Lanturn either charges or uses a normal TBolt, which does (18.3 - 22.2%). At this point Suicune has at MOST taken a maximum of 61,6% with max damage rolls, or it is sitting comfortably at 60,6% complete total health as you have a +2 TBolt coming off.

Turn 5: Suicune uses Calm Mind (+5) - Lanturn uses +2 TBolt - it does (31.1 - 37.1%). Suicune currently has a minimum of 29,75% HP. Either rest at this point or go for the last CM.

At this point, I would just spam Scald until I'd need to rest again (otherwise you'd be healing Lanturn when it struggles), and repeat until I had about ~10 of them left. Of course, only using STalk every other turn as well. This adds up to a total of this:

.. Suicune has a total of (16 + 16 + 24 + 32) PP + an additional 16 from using Rest w/o STalk. Totals up at 104 turns, and it has the high likelyhood of getting either frozen or fully paralyzed given who it is up against.

Lanturn has a total of (32 + 16 + 24 + 24) PP = Totals up at 96 turns.

By the way, a Lanturn Magnet CRIT does 81.6 - 96.5% to 252 HP / 0 SpD Suicune, so it can technically survive it and rest off the damage provided it has gotten to set up. All depends on the hax gods - but CroCune can beat that Lanturn set :>

Garchomp @ Yache Berry
Ability: Rough Skin
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature
- Swords Dance
- Outrage
- Earthquake
- Fire Fang​

CHOMPCHOMPCHOMP

252 SpA Thundurus-T Grass Knot (80 BP) vs. 4 HP / 0 SpD Garchomp: 108-128 (30.1 - 35.7%)
4 Atk Thundurus-T Superpower vs. 4 HP / 0 Def Garchomp: 95-112 (26.5 - 31.2%)

252 Atk Garchomp Outrage vs. 0 HP / 0- Def Thundurus-T: 294-346 (98.3 - 115.7%)
+2 252 Atk Garchomp Outrage vs. 0 HP / 0- Def Thundurus-T: 586-690 (195.9 - 230.7%)

Also punishes Thundurus-T for using U-turn with Rough Skin.

Good luck trying to counter this, folks! Unfortunately, there are two Pokemon I can think of that can counter it this Gen. Isn't that boring?

 

[TrainerNico]

Cryogonal@Life Orb
Nature:Timid
Ability: Levitate
252 SpA / 252 Spe / 4 SpD
-Ice Beam
-Flash Cannon
-Rapid Spin
-Recover

252 SpAtk Life Orb Cryogonal Ice Beam vs 4 HP/0 SpDef Yache Berry Garchomp: 103.91% - 122.35%

Cryogonal outspeeds Garchomp then OHKO it with Ice Beam

 

[Jin Of The Gale]

Cryogonal outspeeds Garchomp then OHKO it with Ice Beam

Cryogonal gets OHKO'd when it switches into any of Garchomp's offensive moves. It's a check, not a counter.

Heatran (F) @ Air Balloon
Trait: Flash Fire
EVs: 252 HP / 4 Def / 252 SAtk
Modest Nature (+SAtk, -Atk)
- Fire Blast
- Earth Power
- Dragon Pulse
- Hidden Power [Grass]

Heatran can switch into Fire Fang and Earthquake safely without getting hit thanks to Flash Fire and Air Balloon. It 2HKOs Garchomp with Dragon Pulse when it's locked into Outrage.

252 Atk Garchomp Outrage vs. 252 HP / 4 Def Heatran: 93-110 (24 - 28.4%) -- 97.1% chance to 4HKO

252+ SpA Heatran Dragon Pulse vs. 4 HP / 0 SpD Garchomp: 234-276 (65.3 - 77%) -- guaranteed 2HKO

 

[Dark Azelf]

By the way, a Lanturn Magnet CRIT does 81.6 - 96.5% to 252 HP / 0 SpD Suicune, so it can technically survive it and rest off the damage provided it has gotten to set up. All depends on the hax gods - but CroCune can beat that Lanturn set :>

Yah it wins cos of pressure. Also is that the old way crits worked aka x2 or the gen 6 way aka only 1.5x?

Anyway,

Snorlax@Leftovers
168 HP / 120 Def / 220 Sp.Def
Careful Nature
Trait: Thick Fat (see: your mom)
- Curse
- Rest
- Body Slam
- Fire Punch

Heatran cant do anything against this and just Curses and Rests off any damage and then nails it with attacking move.

 

[Nah]

For some strange reason I thought that Charge boosted Sp.Attack, not Sp.Defense.

If my brain still isn't in dumbass mode, this should counter Snorlax:

-Conkeldurr w/Leftovers
Ability: Guts
Nature: Adamant
EVs: 252 HP, 252 Attack, 4 Sp.Defense
Moves: Bulk Up, Drain Punch, Mach Punch, Ice Punch/Payback

Conkeldurr has the bulk to take Snorlax's attacks, and can heal off damage with Drain Punch+Leftovers. Can alternate between Drain Punch and Bulk Up to eventually kill Snorlax. Guts is there on the off-chance that Fire Punch burns it (and I guess it works if Body Slam paralyzes it).

 

[Jin Of The Gale]

Try not to add slashes. Theoretically, I could put Lucario or Gengar with every possible move they can learn and have no true counters.

Reuniclus (F) @ Leftovers
Trait: Magic Guard
EVs: 104 HP / 252 Def / 152 SAtk
Modest Nature (+SAtk, -Atk)
- Psychic
- Shadow Ball
- Recover
- Focus Blast

152+ SpA Reuniclus Psychic vs. 252 HP / 4 SpD Conkeldurr: 414-488 (100 - 117.8%) -- guaranteed OHKO

252+ Atk Conkeldurr Payback (50 BP) vs. 104 HP / 252 Def Reuniclus: 122-144 (31.5 - 37.2%) -- 78.8% chance to 3HKO

 

[Hiatus]

Jirachi @ Leftovers
Trait: Serene Grace
EVs: 244 Atk/ 200 HP/ 64 Def
Adamant Nature (+Atk, -SAtk)
- Iron Head
- Thunder Wave
- Wish
- Protect

Jirachi wouldn't be taking much damage from any of Reuniclus' attacks. Even if it does, though, it should always be able to recover itself with the combination of Wish and Protect. Then, it could slow down Reuniclus with Thunder Wave and eventually have it taken down with Iron Head.
