Hello everyone. Today I will reveal some of the strongest and most powerful sets available that nobody is using. Normally I wouldn't actually post sets until a tour is over (OMCL) in this case but I realised that these sets are so good that it doesn't really matter if your opponent knows them, because they will be paralysed by the sheer power behind some of the machinations operating behind these mons. The way I make sets is through The Vision™. Basically, I think of what role(s) I want the mon to do and make the set around that. Obviously outside The Vision™, the sets will look underwhelming because that's outside the scope of engineering, but if you stick with the designated roles, I think these sets will perform exceptionally (terms and conditions apply).
1. Big Offense from #1 least offensive player in BH
1.1 Weakness Policy Abomasnow

Abomasnow-Mega @ Weakness Policy
Ability: Simple
Tera Type: Grass
EVs: 252 HP / 252 Atk / 252 Def / 252 SpA / 252 SpD / 252 Spe
Lonely Nature
- Shift Gear
- Raging Fury
- Headlong Rush / Precipice Blades / Bolt Strike
- Grass Knot / Any Grass Move
This first set is all about abusing Simple and Weakness Policy. Abomasnow is a Pokemon of many weaknesses, Bug, Rock and Poison being three of them. The idea is you want to lead/go to this against a RegenVest. Your unsuspecting opponent is hopefully going to click U-turn, Stone Axe or Mortal Spin as you click Shift Gear. This will instantly make give +6 attack, +4 sp.attack and +4 speed.
That's just the beginning. This is also anti-Imposter. Basically, as long as you are healthy enough (can be achieved by running Horn Leech of Matcha Gotcha if you want), you basically force Imposter to click Raging Fury to kill you. Raging Fury is a 2-3 turn move which means that if you are knocked out by Imposter, you have 1 free turn. So how do you abuse this? Well, we simply run a Heart Swap mon with either Prankster or Fire-immunity. The easiest example is WBB/Prankster

with Heart Swap, Judgment, Secret Sword/Collision Course and Sludge Bomb. You are guaranteed to get the Heart Swap and continue your sweep with your now +6/+4/+4 Arceus.

1.2 Auramaxxing No Guard Kyurem + Tailwind Zekrom

Kyurem-White @ Heavy-Duty Boots / Expert Belt
Ability: No Guard
Tera Type: Dragon
EVs: 252 HP / 252 Def / 252 SpA / 252 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Blizzard
- Sandsear Storm / Precipice Blades
- Magma Storm / V-create / Focus Blast / Dynamic Punch
- Zap Cannon

Zekrom @ Eject Button / Life Orb / Leftovers
Ability: Wind Rider
Tera Type: Dragon
EVs: 252 HP / 252 Atk / 252 Def / 252 SpA / 252 SpD / 252 Spe
Naughty Nature
- Tailwind
- Glaive Rush / Glacial Lance
- Volt Switch / Bolt Strike
- Bolt Strike / Recovery
I think Tailwind is an interesting setup move that could be used in offense. It has some pros and cons to Sticky Web. Firstly, it's equivalent to +2 speed compared to +1 which means you can run slower mons. For example, neutral base 70s have 239 speed which is way too slow at +1 but actually is fast enough at +2 (360 vs 480). Another big difference is that Tailwind actually works against Imposter unlike Sticky Web and can't be ignored via Flying-types and Boots. Imposters will copy your mon so the speed drop does nothing. However, Tailwind affects your field so when Imposter comes in, it doesn't copy it. Finally, you get the Tailwind immediately on your next turn whereas you have to wait until your opponent switches out to get your "speed boost". The obvious big downside is that Tailwind really only lasts 3 turns whereas you can set webs and forget about it until they remove it.
This No Guard Kyurem set is pretty standard, I think Ice + Electric + Ground + Fire is the best combination you can get right now. There are a couple of other moves you could consider like Precipice Blades for ground or V-create for fire. There's also Fighting which could replace fire if you need easier improof, but it's the worst typing option. It just so happens that Sandsear Storm and Blizzard are Wind-moves which synergises with Wind Rider. Precipice Blades is better vs Scales Groundceus and V-create (or Population Bomb) is better vs Ice Scales in general but you can't go wrong with Magma Storm. I also think if you wanna run this as breaker you need a damage item but I guess Boots could work if you hazard stack or if you get lucky with paralysis.

For the Zekrom, there are a couple of options too. On offense I think you just run no recovery, Tailwind + 3 attacks. Best case scenario is switching into a Wind move and clicking Tailwind to be at +2 attack and speed. Glaive Rush is the standard Dragon STAB but you can actually run Glacial Lance to hit Ting-Lu and Dragons. Ice + Electric is basically optimal outside of a few cases. You'll always outspeed Imposters too so they can't just go into that without taking a lot of damage. If you want to run this in balance then you can slot in a recovery. There is also a bit of fun stuff you can try with Eject Button. You can click Tailwind and Eject Button out immediately to your nuke, bringing it safely and gaining an extra Tailwind turn.

1.3 "The Invincible" SD Prank Fly Ho-oh

Ho-Oh @ Lagging Tail
Ability: Prankster
Tera Type: Fire
EVs: 252 HP / 252 Atk / 252 Def / 252 SpA / 252 SpD / 252 Spe
Hasty Nature
- Swords Dance / Destiny Bond / Recovery
- Copycat
- Fly
- V-create
Ok so I haven't actually tested this but the idea is simple. Lagging Tail makes your Pokemon go last on their priority bracket. What you want to do is to click Fly (or any 2-turn invulnerability move like Dive or Shadow Force) and then Copycat that Fly. What should happen is that the 2nd (damaging part) of Fly will occur LAST on the +0 priority bracket which means your Ho-oh will go last and avoid your opponent's attack. On the next turn, your Copycat will select Fly and your Ho-oh will perform the first (become untargettable) phase of Fly LAST on the +1 priority bracket which means you're still gonna go first unless y our opponent clicked a priority move. I also think you're self-proof in some cases. This set also has V-create if you just wanna spam Copycat V-creates instead. Now there are some things that will ruin this setup like non-zero priority moves (Dragon Tail/Circle Throw being the most common and Prankster). There is also Knock Off and your opponent can easily recover between turns.

1.4 Simple Plot Belch Eternatus

Eternatus @ Jaboca Berry
Ability: Simple
Tera Type: Poison
EVs: 252 HP / 252 Def / 252 SpA / 252 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Belch
- Secret Sword
- Strength Sap
Won't go into too much detail here, It's basically self proof Simple NP sweeper that doesn't care about Knock Off which is nice. You do have to Knock Off/status the Imposter before hand though.
2. "Help I need to switch into Regens and stop them from U-turning into their nuke for free"
2.1 Guts Fake Out/Espeed Ursaluna

Ursaluna @ Flame Orb
Ability: Guts
Tera Type: Ground
EVs: 252 HP / 252 Atk / 252 Def / 252 SpD / 252 Spe
Adamant Nature
- Facade
- Precipice Blades
- Fake Out / Extreme Speed
- Strength Sap
Basically Guts Ursaluna come in for free on most Regen moves except Salt Cure since you don't care about item or status. if you run Fake Out or Extreme Speed, you can now threaten fast nukes who usually don't have healing. Fake Out basically stops every single choiced mon from coming in whereas Espeed is double damage but isn't as free to click. I'm not sure if you want speed or not to be honest. Being faster than regens mean they can't click U-turn since they'll take a lot of damage but being slower also means they can't U-turn because the incoming mon will take the hit instead. Might be team dependent but I'd say you should have speed to attack Regens twice.
252+ Atk Guts Ursaluna Facade (140 BP) vs. 252 HP / 252 Def

Celesteela: 153-181 (38.4 - 45.4%) -- guaranteed 3HKO
252+ Atk Guts Ursaluna Facade (140 BP) vs. 252 HP / 252 Def

Ting-Lu: 270-318 (52.5 - 61.8%) -- guaranteed 2HKO
252+ Atk Guts Ursaluna Facade (140 BP) vs. 252 HP / 252 Def Fur Coat

Zamazenta: 144-169 (37.1 - 43.5%) -- guaranteed 3HKO
2.1 MISTY SURGE Belch Eternatus

Eternatus @ Jaboca Berry
Ability: Misty Surge
Tera Type: Poison
EVs: 252 HP / 252 Def / 252 SpA / 252 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Belch
- Nasty Plot
- Secret Sword
- Strength Sap
Return of Belch Etern now with extra Misty Terrain Support for the rest of your team.
2.2 Toxic Debris Steelix

Steelix-Mega @ Rocky Helmet
Ability: Toxic Debris
Shiny: Yes
Tera Type: Steel
EVs: 252 HP / 252 Atk / 252 Def / 252 SpD
Relaxed Nature
IVs: 0 Spe
- Precipice Blades
- Salt Cure
- Pain Split
- Court Change
Steelix is the perfect bait for Garchomp and Blaziken... except the moment your opponent tries to U-turn into it, they can't bring them in because of Toxic Spikes. By making your Toxic Debris mon anti-regen, you can put your opponent into awkward positions because their spinner and pivot gives you free hazards. This Steelix also beats some Eternatus sets which is nice.
2.3 Electromorphosis Zekrom

Zekrom @ Choice Scarf/ Choice Band
Ability: Electromorphosis
Tera Type: Dragon
EVs: 252 HP / 252 Atk / 252 Def / 252 SpA / 252 SpD / 252 Spe
Naughty / Naive Nature
- Volt Switch
- Bolt Strike
- Glaive Rush / Glacial Lance
- Trick
This one only walls non-Mortal Spin and Salt Cure regens (Exactly Rapid Spin/Revdance/Nuzzle/U-turn) but it's kinda cool because Electromorphosis doubles your next electric move which is a lot of damage. With just Scarf it's a +2 but if you run Choice Band, it's actually equivalent to +4 which is a 3x multiplier. The bad part about Band is that you don't actually threaten a lot of offensive mons since you are slow but with +speed, you can outspeed 100s which is kind of ok.
