Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 108 HP / 184 SpA / 216 Spe
Timid Nature
- Hydro Pump
- Volt Switch
- Thunderbolt
- Will-o-Wisp

Wash comes in on most of the moves, only being 2HKO at +2 by Bounce. Thunderbolt does about as much as you would expect. Also Rotom outspeeds it passively. Would be different if previous post mentioned Power whip.


+1 252 Atk Gyarados Bounce vs. 108 HP / 0 Def Rotom-Wash: 96-113 (35.8 - 42.1%) -- guaranteed 3HKO

184 SpA Rotom-Wash Thunderbolt vs. 0 HP / 4 SpD Gyarados: 480-568 (145 - 171.6%) -- guaranteed OHKO

Ferrothorn @ Leftovers
Ability: Iron Barbs
EVs: 252 HP / 24 Def / 232 SpD
Sassy Nature
- Spikes
- Leech Seed
- Gyro Ball
- Power Whip

Calcs:

Against Ferrothorn:

With Burn:
With Leech Seed:
184 SpA Rotom-Wash Hydro Pump vs. 252 HP / 232+ SpD Ferrothorn: 48-57 (13.6 - 16.1%) -- possibly the worst move ever
184 SpA Rotom-Wash Volt Switch vs. 252 HP / 232+ SpD Ferrothorn: 30-36 (8.5 - 10.2%) -- possibly the worst move ever
184 SpA Rotom-Wash Thunderbolt vs. 252 HP / 232+ SpD Ferrothorn: 39-47 (11 - 13.3%) -- possibly the worst move ever

Without Leech Seed:
184 SpA Rotom-Wash Hydro Pump vs. 252 HP / 232+ SpD Ferrothorn: 48-57 (13.6 - 16.1%) -- possible 7HKO after Leftovers recovery and burn damage
184 SpA Rotom-Wash Volt Switch vs. 252 HP / 232+ SpD Ferrothorn: 30-36 (8.5 - 10.2%) -- possibly the worst move ever
184 SpA Rotom-Wash Thunderbolt vs. 252 HP / 232+ SpD Ferrothorn: 39-47 (11 - 13.3%) -- possible 8HKO after Leftovers recovery and burn damage

Without Burn:
With Leech Seed:
184 SpA Rotom-Wash Hydro Pump vs. 252 HP / 232+ SpD Ferrothorn: 48-57 (13.6 - 16.1%) -- possibly the worst move ever
184 SpA Rotom-Wash Volt Switch vs. 252 HP / 232+ SpD Ferrothorn: 30-36 (8.5 - 10.2%) -- possibly the worst move ever
184 SpA Rotom-Wash Thunderbolt vs. 252 HP / 232+ SpD Ferrothorn: 39-47 (11 - 13.3%) -- possibly the worst move ever

Without Leech Seed:
184 SpA Rotom-Wash Hydro Pump vs. 252 HP / 232+ SpD Ferrothorn: 48-57 (13.6 - 16.1%) -- possibly the worst move ever
184 SpA Rotom-Wash Volt Switch vs. 252 HP / 232+ SpD Ferrothorn: 30-36 (8.5 - 10.2%) -- possibly the worst move ever
184 SpA Rotom-Wash Thunderbolt vs. 252 HP / 232+ SpD Ferrothorn: 39-47 (11 - 13.3%) -- possibly the worst move ever

Against Rotom-Wash:

With Burn:
With Leech Seed:
0 Atk burned Ferrothorn Power Whip vs. 108 HP / 0 Def Rotom-Wash: 117-138 (43.6 - 51.4%) -- 99.6% chance to 2HKO after Leech Seed damage

Without Leech Seed:
0 Atk burned Ferrothorn Power Whip vs. 108 HP / 0 Def Rotom-Wash: 117-138 (43.6 - 51.4%) -- 8.2% chance to 2HKO

Without Burn:
With Leech Seed:
0 Atk Ferrothorn Power Whip vs. 108 HP / 0 Def Rotom-Wash: 234-276 (87.3 - 102.9%) -- 18.8% chance to OHKO after Leech Seed damage

Without Leech Seed:
0 Atk Ferrothorn Power Whip vs. 108 HP / 0 Def Rotom-Wash: 234-276 (87.3 - 102.9%) -- 18.8% chance to OHKO

This set mainly relies on Leech Seed. Ferrothorn comes in and gets Burned. On the next turn, Ferrothorn uses Leech Seed. Since Hydro Pump 7HKOes without Leech Seed and Burn damage (Thunderbolt is even worse), Ferrothorn survives. Ferrothorn then proceeds to 2HKO/OHKO with Power Whip.

I get to use one of my favourite CAP Pokemon:

Stratagem @ Choice Specs
Ability: Levitate
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Paleo Wave
- Fire Blast
- Earth Power
- Energy Ball

I’m afraid it’s way too easy to counter.

Calcs:

Against Stratagem:

0 SpA Pyroak Lava Plume vs. 4 HP / 0 SpD Stratagem: 55-66 (17 - 20.4%) -- possible 5HKO

Against Pyroak:

252 SpA Choice Specs Stratagem Paleo Wave vs. 248 HP / 8 SpD Pyroak: 426-504 (96.1 - 113.7%) -- 75% chance to OHKO after Leftovers recovery

Pyroak Lava Plume only 5HKOes, whereas Stratagem OHKOes straight with Paleo Wave.

Here's the worst looking mon ever created

Grimmsnarl (M) @ Leftovers
Ability: Prankster
EVs: 248 HP / 252 SpD / 8 Spe
Careful Nature
- Bulk Up
- Darkest Lariat
- Rest
- Sleep Talk
shoutouts Mellow , actually passed me this set yesterday for a team lol

252 SpA Choice Specs Stratagem Paleo Wave vs. 248 HP / 252+ SpD Grimmsnarl: 169-201 (43 - 51.1%) -- guaranteed 3HKO after Leftovers recovery
0 Atk Grimmsnarl Darkest Lariat vs. 4 HP / 0 Def Stratagem: 153-180 (47.5 - 55.9%) -- 78.5% chance to 2HKO

Thanks to Prankster, Grimm can just continuously Rest when it gets low and fish for enough Darkest Lariats to kill and can maybe get some Bulk Ups in the process. Note there is 1 scenario in which Stratagem has a very small chance to 2hko Grimmsnarl and that is in the turns after Dynamax ends when Strata regains it's Choice Specs boost and has set SandStorm with Max Rockfall (4.7% chance to 2HKO after sandstorm damage and Leftovers recovery ). Grimm can avoid this by blowing its Dynamax if it somehow hasn't killed Stratagem already.

Strata was surprisingly hard to find a hard counter for under the circumstances of perfect prediction, though in a real game it is much easier to deal with thanks to scouting etc.

Weezing-Galar @ Black Sludge
Ability: Misty Surge
EVs: 252 HP / 152 Def / 88 SpD / 16 Spe

0 Atk Grimmsnarl Darkest Lariat vs. 252 HP / 152+ Def Weezing-Galar: 20-24 (11.6 - 13.9%) -- possible 8HKO

Burned W/ No Boosts
0 Atk burned Grimmsnarl Darkest Lariat vs. 252 HP / 152+ Def Weezing-Galar: 10-12 (5.8 - 6.9%) -- possibly the worst move ever

Healthy + 2 Boosts
+2 0 Atk Grimmsnarl Darkest Lariat vs. 252 HP / 152+ Def Weezing-Galar: 39-46 (22.6 - 26.7%) -- 29.5% chance to 4HKO

Weezing
0- SpA Weezing-Galar Sludge Bomb vs. 248 HP / 252+ SpD Grimmsnarl: 134-158 (34 - 40.2%) -- 33.4% chance to 3HKO after Leftovers recovery

Misty Surge prevents Rest. Weezing speed creeps Grimm.

Tyranitar @ Assault Vest
Ability: Sand Stream (I did indeed, thank you for the catch, かたわれ時!)
EVs: 224 HP / 32 Att / 252 SpD
Careful Nature
- Rock Slide
- Crunch
- Payback
- Earthquake

32 Atk Tyranitar Payback (100 BP) vs. 0 HP / 0 Def Indeedee: 458-542 (175.4 - 207.6%) -- guaranteed OHKO
252 SpA Choice Specs Indeedee Energy Ball vs. 224 HP / 252+ SpD Assault Vest Tyranitar in Sand: 82-98 (20.6 - 24.6%) -- guaranteed 5HKO

Sucks Pursuit has gone :( - Payback and Crunch both do the business. Payback replicates the Pursuit Trap by penalising the enemy when it switches in with 100BP Stab and Sand to Chip.

I think you mean Sand Stream on the Tyranitar.

Arghonaut @ Leftovers
Ability: Unaware
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Bulk Up

Calcs:

Against Arghonaut:

32 Atk Tyranitar Rock Slide vs. 252 HP / 0 Def Arghonaut: 55-66 (13.2 - 15.9%) -- possible 7HKO after sandstorm damage and Leftovers recovery
32 Atk Tyranitar Crunch vs. 252 HP / 0 Def Arghonaut: 59-70 (14.2 - 16.9%) -- possible 6HKO after sandstorm damage and Leftovers recovery
32 Atk Tyranitar Payback (100 BP) vs. 252 HP / 0 Def Arghonaut: 74-87 (17.8 - 21%) -- possible 5HKO after sandstorm damage and Leftovers recovery
32 Atk Tyranitar Earthquake vs. 252 HP / 0 Def Arghonaut: 99-117 (23.9 - 28.2%) -- 94.2% chance to 4HKO after sandstorm damage and Leftovers recovery

Against Tyranitar:

252+ Atk Arghonaut Drain Punch vs. 224 HP / 0 Def Tyranitar: 444-528 (111.8 - 132.9%) -- guaranteed OHKO
252+ Atk Arghonaut Aqua Jet vs. 224 HP / 0 Def Tyranitar: 116-140 (29.2 - 35.2%) -- 18.7% chance to 3HKO
252+ Atk Arghonaut Gunk Shot vs. 224 HP / 0 Def Tyranitar: 59-69 (14.8 - 17.3%) -- possible 6HKO

Tyranitar only 4HKOes at best with Earthquake, and at 100 BP Payback only 5HKOes. Meanwhile Arghonaut OHKOes with Drain Punch. If you want to be cruel, you can even set-up on the opponent :)

Also hi I've been a long time lurker on CAP and with Gen 8 I decided I'll finally put myself out there, so first post.
EDIT: Yes I know this is an eh Corv set, but it was meant for killing the Argho

Hey, Unfortunately, this is a YUCK as it actually loses 1v1 to the Rotom set. Since the OP specifies perfect prediction, we can assume Rotom Nasty Plots as Cursola switches in. From there both Pokemon Dynamax, Cursola using Max Phantasm (252+ SpA Life Orb Cursola Shadow Ball vs. +2 240 HP / 0 SpD Rotom-Heat: 156-185 (51.8 - 61.4%) -- guaranteed 2HKO ) as Rotom Goes for Max Flare setting sun. Since Rotom is faster and Max Flare didn't drop its SpA, the 2nd Sun Boosted Max Flare will kill Cursola.

+2 52 SpA Rotom-Heat Overheat vs. +2 252 HP / 0 SpD Cursola in Sun: 198-234 (61.1 - 72.2%) -- guaranteed 2HKO

also, a quick reminder that the OP states viable sets. This game is a lot easier if you tailor-make sets for the situation, makes it a lot more fun and challenging if we try to stick with things that could actually be used (not directly aimed at the above set, just in general)

Toxic and Scald burns aren't gonna faze Clef, and Clef pretty comfortably beats Quag, especially if it doesn't switch into EQ. Even if it does switch into EQ, it still wins.
