SS OU Good Cores Thread

A strong core is one of the single most valuable things to form when creating a new team. Cores are typically made up of a group of Pokémon that, when used together, work excellently toward accomplishing a specific goal, and any good player uses them, intentionally or not. The majority of cores have varying characteristics that allow them to triumph in different areas, and depending on your team, cores can be built to succeed offensively or defensively. An offensive core is a group of Pokémon that are both focused towards and designed to enable the team to break through most other team styles while being balanced for general play. A defensive core is a group of Pokémon chosen to give a team a solid set of resistances and the ability to switch into many of the common and threatening attacks in the metagame, allowing it to stick around long enough to win the match. Overall, cores function as a fantastic base or starting point for a wide range of teams and they are commonly used while teambuilding to achieve a specific goal.

:iron-valiant: Posting Guidelines
  • Any person can post a core in this thread. The cores are broken down into four categories: offensive cores, balanced cores, defensive cores, and weather cores. When posting your core, please make sure to state which one of these categories your core falls under.
  • Although the way your core works may be obvious to you, this may not be the case for others. As such, when posting a core, please make sure to explain how the core operates and any other details you think are important to include. The explanations don't have to be essays; as long as your post has some substance and conveys the main idea behind the core, it's all good. Here are some things you may like to include when explaining your core:
    • Offensive Core: Should your core be an offensive one, such as Tapu Lele + Kartana, you could explain how those two Pokemon work together to break down their similar checks and any other synergistic traits. You could also mention any weaknesses the core has and any partners you believe work well with the core.
      • Here is a good example of what we look for taken from the ORAS iteration.
    • Defensive Core: Should your core be defensive, such as Hippowdon + Skarmory, you could explain their typing synergy allows them to cover problematic Pokemon for one another, or any other synergistic attributes you feel are relevant. You could also mention any weaknesses the core has and any partners you believe work well with the core.
      • Here is a good example of what we look for taken from the ORAS iteration.
  • This goes without saying, but do make sure your post includes the sets your core is using. In addition, please try to include an explanation of any EV spreads deviating from the standard 252 / 252. Replays are also very helpful and highly encouraged when posting cores.
  • Please do not post a core that has more than 3 Pokemon because cores bigger than this can restrict building immensely.
  • Please be respectful of the cores people post in this thread. If someone posts a core that you think is ineffective or just plain bad, there is no need to jump at their throats. With that said, constructive criticism is welcome and encouraged - simply be nice!
:tapu-koko: Core Selection Process
  • I will carefully monitor the cores posted in this thread. When the time comes, I will look at the posted cores and decide which ones will be featured in the archive.
  • While the selection of good cores can often be subjective, I will take into consideration a variety of aspects before deciding which cores are featured in the archive. This includes quality of explanation, effectiveness of the core in the current metagame, and so on. I will carefully discuss everything and seek feedback from others to ensure the selected cores are of high quality.
  • When I decide which cores will be featured in the archive, I will try to announce them and provide brief explanations behind why certain cores were selected and why certain cores weren't. This feedback can potentially help give people a clearer picture of what we are looking for.
  • If a core is originally rejected from the archive, I can definitely provide some tips on how a set or spread can be tweaked so the core meets the standards we look for.
  • Just like with anyone else who posts a core, please feel free to bring up any concerns you might have with our posts and/or the cores we select! However, please be sure to be polite, and if it is a simple question/concern, we'd prefer it being directed to us in a PM.
Submissions are very, very appreciated right now; please send any you think would be good!
 
Offensive Cores
These cores are ones that feature offensively pressuring towards opponents, often being built around initially.
In progress of a massive update!

Balanced / Defensive Cores
These cores often are used to balance out a team, or to provide a solid defensive backbone to be built around / added to one.
In progress of a massive update!

Offensive Core:
Zama + Lele
Who can take a Future Sight + Tera Fighting Close Combat? (okay gholdengo and other ghost types can, but that's what crunch is for) Would be AV lele but I'm too lazy to explain that + scarfed lele is good overall so ye.

Will def add more cores soon mostly cuz it's too late now.
 
Balance Core:
Mega Lopunny and Gholdengo

Gholdengo covers all of Mega Lopunny's weaknesses and Mega Lopunny covers two of Gholdengo's weaknesses.
Gholdengo pressures defensive Pokemon while Mega Lopunny is strong against offensive ones.
Both Pokemon resist Stealth Rock while Gholdengo is completely immune to status moves.
Nothing is immune to Mega Lopunny's attacks bar tera Ghost, Neutralizing Gas Weezing.
Mega Lopunny's Fake Out and U-Turn provide chip for Gholdengo.
Mega Lopunny can sponge Knock Off due to its Dark-type resistance and Mega Stone.

I call it this a balance core because while Mega Lopunny is expected to attack every turn, Gholdengo can use select opportunities to Recover.
Trick is required because it ruins defensive Pokemon, while specs is preferred because it gives Gholdengo bite with Shadow Ball/MIR while crippling physical attackers.
Two attacking moves are required in case of Tricking on an Assault Vest.

It's a high-floor, high ceiling duo: newbies can just ride on Gholdengo's defenses, while experts can exploit Mega Lopunny's typing to create favorable matchups.
 
Revamp!
The list of cores has now been expanded, featuring over 50 cores that you can use to aid you with teambuilding. I hope you enjoy utilizing this resource! If you feel like some other cores should be added, be sure to submit them in this thread!
 
Balance trick room core:
:ursaluna: :Slowking:
https://pokepast.es/0978d45c475f68b7
With trick room and teleport Slowking realy helps ursaluna to get in the game and start hammering away at the opponent with boosted flame orb guts facades explecialy with tera added vs offensive team on wile Slowking has a lot of longevity with Regenerator slack off and Heavy-Duty Boots to support it during a game
Alternative moves:

Slowking can swap scald for future sight to support other team members u might have if u wana use this core on a non full trick room team

Ursaluna can swap fire punch for all the other covreg moves u might want like close combat crunch or ice punch

EDIT: Ursaluna got ban so it no longer works

Ok ok i'm nervous and Idk if this is a GOOD core, but here we go. (Pls don't give it to break this core, laddering will be hell if you do) anyways.

mr beast boost (Kartana) @ Fightinium Z
Ability: Beast Boost
Tera Type: Grass
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Leaf Blade
- Sacred Sword
- Knock Off

sailor moon (Cresselia) @ Leftovers
Ability: Levitate
Tera Type: Poison
EVs: 120 HP / 132 Def / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk
- Calm Mind
- Moonlight
- Hidden Power [Fighting]
- Stored Power


This core revolves around Cresselia tanking out and setting up on offensive threats to SD Kart, such as Mega Lopunny, Zama and Iron Valiant. Kartana simultaneously breaks through the special walls and physical attackers that can deal with Cresselia, with Sacred sword to hit dark types and of course, Kingambit. Cresselia can also beat special attackers which may tank a hit from Kartana and make it die instantly (Kart has literally NO special defense), and this can help break offensive teams down.
 
I think a good core for more balanced teams is Baxcalibur+Slowking-Galar+Buzzwole. Bax's Dragon Dance sets are great matchwinners for balance teams, though revenge killers such as Booster Valiant, Tera Dark Kingambit, Scarf Lele, and Mega Scizor can serve a problem for it. Glowking is able to check any revenge killing Fairy type thrown at Bax, and in addition Future Sight and Chilly Reception support deters switch-ins like Valiant and gives Bax passive recovery if running Ice Body. Physical checks are shut down rather easily by Buzzwole, who's great defensive profile and typing allow it to take on the two mentioned physical checks to Bax with ease. Buzzwole synergises well with Glowking because Buzzwole is able to switch into threatening moves like Knock Off and Earthquake directed towards Glowking, while Glowking is able to switch comfortably into the Psychics, Moonblasts, and Flamethrowers directed at Buzzwole. In addition, these two defensive mons are able to reliably check the Pokemon they are meant to multiple times in a game without being worn down (Buzzwole's Roost and Glowking's Regenerator), meaning that they are always available to deal with the checks to Bax and let it DDance for the win.

My Standard Core: https://pokepast.es/e8c59a2f80988f22
 
So, since there has been not much activity here, I wanted to post just a big list of cores I’ve seen to help people with team building and stuff, also gives me a ton of starting points to work with, and I hope other people use it for this purpose too.

This also might be archived cores that I still think work well

I also might add more to this list

Offensive Core
:Tapu Koko: :Hawlucha:
Tapu Koko @ Heavy-Duty Boots
Ability: Electric Surge
Tera Type: Electric
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunderbolt
- Volt Switch / U-Turn
- Roost
- Dazzling Gleam

Hawlucha @ Electric Seed
Ability: Unburden
Tera Type: Flying
EVs: 252 Atk / 4 SpD / 252 Spe
- Swords Dance
- Close Combat
- Acrobatics
- Substitute / Encore

Tapu K sets up Electric Terrain, which gives Hawlucha speed boost with Unburden, pretty simple. Also, Tapu Koko deals with Pokemon that could stop a Hawlucha sweep before it could get going, such as Alomomola, Corviknight, and Zapdos, while Hawlucha breaks down Pokémon that could cause a little bit of trouble for Tapu Koko, such as Ferrothorn, Garganacl, and Slowking-Galar.

This Core would be best on Electric Terrain Offense/Hyper Offense, and I would recommend a Pokémon like Iron Valiant to keep on pressure while also helping with Pokémon that could KO Hawlucha with priority, such as Raging Bolt or Weavile.

Offensive Core
:Ogerpon-Wellspring: :Weavile:

Ogerpon-Wellspring (F) @ Wellspring Mask
Ability: Water Absorb
Tera Type: Water
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Ivy Cudgel
- Power Whip
- Superpower / Play Rough

Weavile @ Choice Band
Ability: Pressure
Tera Type: Dark
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Triple Axel
- Knock Off
- Ice Shard
- Pursuit

As much as you can argue that Ogerpon-Wellspring should have been banned, you can’t argue that it’s very strong in the current metagame, and Band Weavile is a great breaker that can deal with Dragon-types such as Raging Bolt and Dragonite, while also pursuit trapping Mega Latios and Mega Latias, as well as just being a strong wallbreaker. Waterpon also helps Weavile with Pokémon such as Heatran. Waterpon and Weavile can also break down shared checks like Ferrothorn together. These are just 2 strong physical attackers that can just obliterate teams.
 
WIP

So, a month has passed, and I kinda got a lot of cores, so I’m just gonna post a ton of coresthat I’ve seen used, and hopefully, some see it and decide to use it as a starting point.

All poke-pastes are clickable using the sprites. Also I’m probably gonna come back and put explanations for all of these.

Total : 12

Total: 9
Total: 14

6/24/24: Stopping at 25 for Today
7/8/24: got about 10 more, too lazy to count
