Welcome to the USUM edition of the UU Cores thread! The purpose of this thread is for the community to post and discuss various cores that work well in the metagame.


As you all know, a core is a group of usually 2 or 3 Pokemon in the team that work together toward a specific goal. These goals include breaking through opposing teams (Offensive), covering each other's weaknesses while providing the team with a solid set of resistances (Defensive), and checking important threats in the UU metagame while exerting offensive pressure upon the opposing team (Balanced).


All cores are welcome in this thread, as long as they meet the following guidelines:
  1. Cores posted here must be tested to ensure that they perform well in the metagame. Therefore, including replays is recommended to further support the validity of your core. Try to keep slashes to a minimum.

  2. Include a short, concise description or explanation of the core, which should contain the following information:
  • How the core functions
  • How to use the core itself
Please follow the following format when presenting a core:

1. Provide the sprites and names of the Pokemon that make up your core.

2. Include the sets for your Pokemon (preferably in hide tags).

3. Write up a short description of how the core functions.


Here's an example of what a proper submission should look like:

+


Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 248 HP / 84 Def / 176 Spe
Bold Nature
IVs: 0 Atk
- Will-O-Wisp
- Pain Split
- Hydro Pump
- Volt Switch

Scizor @ Fightinium Z
Ability: Technician
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Swords Dance
- Bullet Punch
- U-turn
- Superpower


The combination of Rotom-W and Scizor may be a generic pairing, but it is also one that has procured steady results for many offensive and balance teams from and following the BW era. Rotom-W acts as a general pivot here, checking the vast majority of physically offensive Pokemon by virtue of Will-O-Wisp. It also provides a decent Fire resist and the option to keep up the pace of the game through Volt Switch, both of which complement Scizor. SD + 3 attacks is also a very standard set, and with Fightinium Z, Scizor can function as both a wallbreaker and cleaner, while checking the Grass and Dragon types that Rotom-W may not be able to handle. Basically, this core is a tried-and-true base for many teams and significantly eases the potential strain teambuilding can have, even to this day.

Sceptile-Mega @ Sceptilite
Ability: Lightning Rod
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Leaf Storm
- Dragon Pulse
- Giga Drain
- Hidden Power [Fire]

Infernape @ Choice Scarf
Ability: Blaze
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Flare Blitz
- Close Combat
- U-turn
- Gunk Shot / Stone Edge


This offensive core is built around Mega Sceptile slapping opposing Water-types and Dragon-types like Rotom-W, Swampert, and Latias that Infernape struggles with and Infernape pressuring Steel-types like Scizor, Grass-types like Celebi and Amoonguss, and faster threats like Mega Aerodactyl and Choice Scarf Hydreigon. Infernape also gives more opportunities for Mega Sceptile to come in thanks to U-turn. Overall this core is pretty easy to use and pairs well with other VoltTurn users or Spikes support.



Altaria-Mega @ Altarianite
Ability: Pixilate
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dragon Dance
- Facade
- Earthquake
- Roost

Magneton @ Choice Specs
Ability: Magnet Pull
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunderbolt
- Flash Cannon
- Volt Switch
- Hidden Power [Fire]


Another neat offensive core which is based around Magneton trapping troublesome Steel-types like Scizor, weakened Mega Aggron, and Magnet Rise Klefki, and then having Mega Altaria clean up with your personal preference of Dragon Dance set (I run Adamant Facade because Altaria attracts opposing status effects like flies to honey, it lets you run Earthquake without worrying about opposing status inducers like Rotom-W, and it also just hits ridiculously hard when statused.)

Muk-Alola @ Assault Vest
Ability: Poison Touch
EVs: 248 HP / 112 Atk / 148 SpD
Careful Nature
- Knock Off
- Pursuit
- Poison Jab
- Fire Punch

Serperior @ Leftovers
Ability: Contrary
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Substitute
- Leech Seed
- Leaf Storm
- Hidden Power [Fire]

Serperior was recently unbanned and has proven itself a notable threat in the tier, but it still struggles with a decent number of Pokemon in UU: Dragon-types, Moltres, etc. Muk-Alola can come in on Pokemon like Latias and trap them, paving the way for Serperior to spam Leaf Storm. In return, Serperior can pressure stall with Substitute + Leech Seed and use Leech Seed to keep Muk-Alola healthy. Residual damage from Poison Touch and Leech Seed helps this core wear down teams. The Muk-Alola spread is something I came up with a while ago to stop Modest Primarina from 2HKOing with Hydro Pump after Stealth Rock, but a more generic spread works just fine. Seismitoad and Rotom-W make good partners for this core, as both appreciate Muk-Alola's ability to remove Latias, can check Mega Aerodactyl, and benefit from Leech Seed recovery. Seismitoed can set up Stealth Rock and serve as a hard stop to VoltTurn, while Rotom-W provides pivot support to help Serperior and Muk-Alola switch in safely and can use Defog to clear hazards.



Infernape @ Life Orb
Ability: Blaze
EVs: 168 Atk / 88 SpA / 252 Spe
Naive Nature
- Overheat
- Close Combat
- Grass Knot
- Gunk Shot

Latias @ Choice Scarf
Ability: Levitate
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Draco Meteor
- Psychic
- Hidden Power [Fire]
- Healing Wish

Mixed Infernape is a nice breaker that can put in a lot of work vs. bulkier teams, but doesn't have as much of an impact vs. offense. Choice Scarf Latias does well against offense, but struggles to seriously threaten bulkier Pokemon. Infernape breaks down walls and removes Steel-types for Latias, while Latias revenge kills faster Pokemon that threaten Infernape. In addition, they have decent typing synergy (Infernape resists the Ice-, Dark-, and Bug-type attacks that Latias is weak to, while Latias covers Psychic-, Water-, and Ground-type attacks for Infernape). Finally, stall has enough trouble dealing with mixed Infernape the first time around, and Healing Wish allows it a second chance at breaking and enables the user to be aggressive with Infernape. Latias can run any number of moves in the third slot, such as Defog, Trick, or a coverage move, depending on team composition.



Hippowdon @ Leftovers
Ability: Sand Stream
EVs: 240 HP / 76 Def / 192 SpD
Impish Nature
- Stealth Rock
- Earthquake
- Slack Off
- Toxic / Whirlwind

Stoutland @ Choice Band
Ability: Sand Rush
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Return
- Superpower
- Crunch
- Facade / Pursuit

Aerodactyl-Mega @ Aerodactylite
Ability: Tough Claws
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Stone Edge
- Wing Attack
- Earthquake
- Pursuit / Aqua Tail

Hippowdon + Stoutland + Mega Aerodactyl is the standard sand core. Hippowdon sets up sand and serves as a general purpose wall, providing additional utility through Stealth Rock and either Toxic or Whirlwind. Stoutland provides the team with a breaker or cleaner, depending on matchup, outspeeding anything slower than Choice Scarf users with base 108 Speed under sand and still hitting hard with base 110 Attack and a Choice Band. The choice between Pursuit and Facade depends on whether the player wants Stoutland to function when afflicted with status or trap the frail, offensive Pokemon it threatens out under sand. Aerodactyl provides additional, more reliable speed control and has surprising special bulk in sand. Pursuit is nice for trapping purposes, but Aqua Tail allows Mega Aerodactyl to hit Pokemon like Gliscor and Hippowdon super effectively. Aqua Tail can also replace another coverage move, depending on what the team needs. Mega Aerodactyl can also take advantage of the additional bulk sand confers to set up with Hone Claws and threaten to sweep. Good teammates can check the Water-types that this core struggles with or provide other utility options that teams normally value (Defog, Taunt, cleric support, etc) and include Pokemon like Latias, Rotom-W, Serperior, Klefki, Scizor, Tentacruel, Sylveon, and Empoleon. Reuniclus also makes a good teammate, as Magic Guard makes it immune to sand damage. I've expanded a bit more on how to play sand and use the specific Pokemon in this core here.

Scizor (M) @ Choice Band
Ability: Technician
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Bullet Punch
- U-turn
- Superpower
- Pursuit

Hydreigon (M) @ Choice Scarf
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Dark Pulse
- Draco Meteor
- Fire Blast
- U-turn

Even though Volt Turn isn’t quite as broken as it was pre USUM, it is still in a good spot. This core is a little U-Turn core with Scizor and Hydreigon, two of the best choice users in the tier. Hydreigon can be used as a fire resist, is one of the best scarfers in the tier, has hard hitting stab and U-Turn, while Scizor is one of the best band users in the tier, has U-Turn, priority to make up for its poor speed, and Pursuit. This core is pretty standard on Volt Turn teams and is pretty easy to use and put dents into the enemy team and let your wincon clean up.

I've personally been trying to get various things to work in the last week and I've come to like this offensive core a lot. Talonflame + Serperior + Azumarill is an solid core dating back to the days of XY OU, but with the introduction of Z-moves and USUM move tutors they come with a couple new tricks up their sleeve. Talonflame on its own can be a nightmare for offensive teams lacking Rotom-Wash, Mega Manectric, or Mega Aerodactyl as it is deceptively hard to stop it from setting up against the right Pokemon, and many other threats like Latias and Primarina would much rather not be on the receiving end of +2 Supersonic Skystrike. Talonflame baits in bulky Water-types, Rock-types, or generally bulky physical walls like Swampert, Suicune, and Hippowdon which Serperior loves to come in and get subs on and proceed to throw Leech Seed and Leaf Storm around. Serperior can run a Defogging set if role compression is required, as reliable hazard control is mandatory with the use of Talonflame. Azumarill completes the core by providing a strong physical wallbreaker that can bust up some defensive threats like Swampert and Alomomola to clear the way for a Talonflame sweep. It can also run Ice Punch in the slot where you'd normally see Knock Off or Superpower to pressure Amoonguss for Serperior. A hyper offensive core such as this also comes with two forms of priority as well which is never too shabby. Obviously this three mon core is pretty dedicated to supporting each other only on the offensive spectrum, so it may sometimes struggle with the standard lineup of offense killers like Mega Beedrill, Mega Aerodactyl, Crobat, Latias, and Mega Manectric so some teammates such as Mega Steelix, Hippowdon (just don't run Sand Stream + gen 7 Gale Wings lol), Alolan Muk, Suicune, Togekiss, Sylveon, and Rotom-Wash can potentially create an effective defensive backbone for the team.
