Will of D (Dragonite) @ Loaded Dice
Ability: Multiscale
Tera Type: Normal
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dragon Dance
- Scale Shot
- Extreme Speed
- Earthquake

is the main sweeper of my team. I realized the fact that

learns Scale Shot while playing VGC, so I thought that it would also work on OU, since +1 Scale Shot with 4 hits OHKO(actually 4HKO lol)s

,

,

, etc. Many people didn't expect the move, so I was able to get some free kills.

leads when major lead Pokemons like

,

are about to lead. But, I don't strongly recommend leading

, since

is much better as a lead. You can change the moveset that matches your taste, but I recommend keeping Extreme Speed since priority moves are important in the meta. For nature, use Jolly if you want more speed with just one Scale Shot/Dragon Dance.

Roronoa Zoro (Iron Valiant) @ Booster Energy
Ability: Quark Drive
Tera Type: Dark
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Knock Off
- Swords Dance
- Encore

is the second main sweeper and a wall breaker of this team.

has various sets, so it can confuse the foe player by just existing. Mine is the Encore Swords Dance set, which can be a big threat to stall teams. Although it may be hard to deal with Unaware users like

,

,

, but

can Encore them and lock up their moves and keep attacking. Or, you can just Swords Dance out in front of the foe's scarf-trciked mon(will explain more about this later).
Counters: Most of the stall mons (except for

),

, etc.
Weak to: Fairies(especially

)
Birdramon (Moltres) @ Choice Specs
Ability: Flame Body
Tera Type: Ground
EVs: 224 HP / 252 SpA / 4 SpD / 28 Spe
Modest Nature
- Flamethrower
- Hurricane
- Scorching Sands
- U-turn
You may wonder why I have given specs while looking at this

set. But trust me, this

set is a huge threat to major pokemons in this meta. Well, yes, Stealth Rock can be very annoying, but with the power of Choice Specs,

can 2HKO

(without assault vest) and

with Hurricane, and 2HKO

with Scorching Sands. Also,

can check

(without Stone Edge),

,

with its ability Flame Body. As I said, this set is extremely weak to Stealth Rock, so remember to use it with

.
Counters:

switching in.
Weak to:
Ban me if U can (Zamazenta) @ Choice Band
Ability: Dauntless Shield
Tera Type: Fire
EVs: 252 Atk / 86 Def / 170 Spe
Jolly Nature
- Close Combat
- Stone Edge
- Ice Fang
- Crunch
IronPress set could have been good enough, but since I prefer offensive

, I used it as a Choice Band attacker. If you are good at predicting switch-in, then this set will be a perfect choice for you. Close Combat is a main dealing move, which can kill

s with one shot(if it's not cornerstone lol). Stone Edge is for flying type pokemon like

,

and

. Ice Fang is for

s, which is very annoying nowadays. Crunch is for breaking

cores. For tera, I chose Fire, since Will-O-Wisp is very annoying to deal with. I gave enough speed to outspeed

,

, adamant

with +1 speed,

, etc.

Dr. Eggman (Iron Treads) @ Assault Vest
Ability: Quark Drive
Tera Type: Flying
EVs: 196 HP / 60 SpD / 252 Spe
Jolly Nature
- Ice Spinner
- Earthquake
- Knock Off
- Rapid Spin

is the hazard remover of my team. I gave it Assault Vest, to endure 2 Earth Powers from Timid nature

. And with 196 HP EVs,

can endure 252 atk Pyro Ball from

. Ice Spinner is for

, Earthquake is for various pokemon that are weak to ground. Knock Off, which is very important because it can hit spinblockers like

and threaten them by making their items unusable. But you have to be careful when using it, since it can Knock Off Choice Scarf from Scarf-Tricked Pokemons(will explain more about that later too).
Counters:

Weak to:
Orochimaru (Seviper) @ Choice Scarf
Ability: Infiltrator
Tera Type: Flying
EVs: 252 HP / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Switcheroo
- Toxic
- Final Gambit
- Glare
THE GOAT.
There's a reason I chose

as a suicide lead. It gets Toxic, Final Gambit, Glare, Switcheroo. It gets literally every move that can annoy the foe.

's main role is to give the scarf to the foe's pokemon when they use status moves, and make

or

easier to boost their attack stat.
Here is how you play with

.
Step 1. Examine the foe's team and predict the foe's lead.
Step 2. If foe's lead is about to Stealth Rock or Spikes or do disgusting things like that, click Switcheroo.
Step 3. As the foe's move is fixed to one move, the foe will first panic, then calm down, and switch to other pokemons who are able to hit

.
Step 4. Now's the time. click Glare or Final Gambit.
Clicking Final Gambit in the first place can be a way, too. And if the foe attack with ground type moves(which can hit

2x damage), Scarf-Switcheroo them and then switch too

. It may seem not that easy, but trust me, it is quite useful against

or

.
And with the Infiltrator Ability, it can Final Gambit out bypassing Substitute.
But you have to be careful against faster pokemons like

,
