Overiew
This is an offensive steel core where all the 3 pokemon on the core deal with threats and check each others threats on the core. Heatran with a stall breaker set breaks walls such as chansey,porygon2,toxapex etc that come in the way of AV celesteela. Heatran on the core also provides a valuable fire immunity to the core while also checking threats such as volcarona and Mega charizard Y for the core.
Celesteela on the core with an AV set is used to vastly improve the ground match up since giga drain and Hp Ice takes care of ground teams and AV set allows celesteela to check landorus-I which is a huge threat for steel teams.Celesteela with AV is also a good pivot into special attacks for the core such as vs water teams.Av set functions as Anti-Ground set which improves the match up.
Excadrill on the core is the speed control helping deal with threats like Mega Charizard Y and X,unboosted volcarona, Helping in electric match up and providing electric immunity as well thanks to its part ground typing.Excadrill can also cripple Mega Sableye for the core with toxic thanks to its ability Mold Breaker.
: Offensive heatran set is used here that can set up stealth rock and stall break with magma storm and taunt which completely shuts down walls since taunt prevents recovery moves. Stall breaker set allows heatran to take out walls that may trouble other teammates such as Toxapex,Chansey,Porrygon2 etc. Earth power allows it some decent coverage along with magma storm and it is used to hit opposing heatran and pokemon that resist magma storm such as Toxapex to wear it down. Stealth rock can be set easily since heatran has plenty of resistances and its horrendous weakness to ground is mitigated by air balloon so it can find decent opportunities to set up stealth rock for offensive teammates that appreciate opposing team being worn down.Stone edge can be run in place of stealth rock to check Mega Charizard Y and Volcarona which are otherwise threats to the core.If stone edge is used then 28 evs should be dumped into attack to guarantee OHKO on aforementioned threats[28 Atk / 224 SpA / 4 SpD / 252 Spe ].Toxic can be used in the last slot as wall to cripple walls and wear them down faster in tandem with magma storm.
:This is an AV celesteela set that aims to take out threatening ground types for the core such as landorus and garchomp. It also provides a nice ground immunity to the core and hence it acts as a pivot. Giga drain and Hp ice takes care of most ground types on ground teams. Hp ice takes out landorus-I and giga drain is used for pokemon such as hippowdon and Seismitoad. AV set also puts in work vs water teams where celesteela can threaten water types with giga drain. Earthquake is used for opposing heatran,Air slash can be used to do good damage to fighting types that threaten the core. .Flamethrower allows celesteela to get past steel types such as ferrothorn.
: Excadrill due to its ground typing provides an important electric immunity to the core.So it can check threats like tapu koko for the core. Excadrill with a choice scarf set deals with fire and flying types such as Mega Charizard Y and Volcarona.Iron head and Earthquake are stab moves,earthquake allows it to deal with rotom-wash since mold breaker ignores levitate. Iron head has a nifty 30 percent chance to flinch and is used vs pokemon that resits its earthquake such as tapu bulu.Rapid spin is used to clear off hazards which may wear down teammates. Toxic can be used to cripple Mega sableye and other walls that like to switch into excadrill.
Threats
: Fighting types like Mega Gallade and Keldeo pose a huge threat to this core since the core is open to fighting moves as it lacks any immunity to it.
: Water types like Mega swampert and Azumarill can break this core as Mega swampert threatens heatran and excadrill and celesteela cannot switch in on Mega swampert in rain. Choice banded azumarill doesa number to this core with aqua jet and waterfall.
: Magnezone is a threat to this core on electric mono teams as it can trap and take out celesteela which is OHKO :
252+ SpA Choice Specs Magnezone Thunderbolt vs. 252 HP / 32 SpD Assault Vest Celesteela in Electric Terrain: 468-552 (117.5 - 138.6%) -- guaranteed OHKO
Magnezone can also trap excadrill locked into rock slide and take it out with specs Hp fire:
252+ SpA Choice Specs Magnezone Hidden Power Fire vs. 0 HP / 0 SpD Excadrill: 306-362 (84.7 - 100.2%) -- 6.3% chance to OHKO
Good Teammates:
: Skarmory is a great teammate for this core since it can provide dual hazards in stealth rock and spikes with a suicide lead set, skarmory's dual hazard is really good if heatran is running stone edge in the last slot. The dual hazard allows for hazard stack which is well appreciated by excadrill and other possible offensive teammates.
: Bisharp is another good teammate since it can function as a wall breaker-cum-Sweeper. With swords dance it breaks down walls and provides utility support with knock off to the core.Bisharp also deteres defog users if skarmory is used with dual hazards.
: Scizor-Mega is a fantastic set up sweeper since its typing allows it to set up vs plethora of types and its weakness is covered by heatran on the core.
:Magnzeone is a decent teammate for the core to check fighting types like keldeo with a choice scarf set, it can also trap and take out annoying walls like ferrothorn or skarmory for offensive teammates, while providing volt switch support to bring in teammates.

Since a core around Mega beedrill is needed, here is one:
Offensive Poison Core

Beedrill-Mega @ Beedrillite
Ability: Adaptability
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- U-turn
- Poison Jab
- Drill Run
- Knock Off /Pursuit

Nidoking (M) @ Life Orb
Ability: Sheer Force
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Stealth Rock
- Earth Power
- Ice Beam
- Flamethrower

Overview:
This is an offensive poison core around Mega beedrill where Nidoking helps to ease off the steel match up where mega beedrill struggles. Mega beedrill and Nidoking is a good core as both the pokemon take out each others checks. Nidoking on the core also provides stealth rock support which is appreciated by mega beedrill to score easy KOs, Mega beedrill on the other hand takes care of psychic types that trouble nidoking while providing U-turn support to bring in nidoking safely.I dont think the sets needs much explanation since the sets are standard so I will skip to good teammates section.
Good teammates:
: Since the core is weak to ground types and ground moves,crobat is a great teammate since it provides a ground immunity thanks to its part flying typing. Crobat also provides defog support to Mega beedrill which is susceptible to hazards.
: Evioltie Golbat can be used as well in place of crobat since it not only provides U-turn and defog support like crobat but eviolite golbat is much bulkier and so it can check threats like Mega Pinsir as well.
: Muk-alola is a must to have since it comprises roles on a poison team such as Psychic type check and a sp.def pivot. Since the above core lacks a switch in to psychic types such as latios,Muk-alola does a good job of dealing with such psychic types while providing knock off support to cripples item reliant pokemon such as chansey or porygon2, something where poison struggles.
: Toxapex is another good teammate since it can check set up sweepers like volcarona,Scizor and bisharp with haze which can prove to be troublesome otherwise. Toxapex can provides toxic spikes support to the core which gradually wears down teams and makes cleaning easier.
:Since Mega Beedrill is used, Mega venusaur cannot be utilized so using Amoongus as a pivot to physical attacks aimed at mega beedrill and nidoking is a good option. Amoongus has spore which is one of its selling point, the ability to cripple a pokemon can be huge in battles, if using toxapex then amoongus forms a great regenerator core with it that can be annoying to break.
 
Offensive Ice Core


Lapras @ Choice Specs
Ability: Water Absorb
EVs: 80 HP / 252 SpA / 176 Spe
Modest Nature
IVs: 0 Atk
- Hydro Pump
- Surf
- Freeze-Dry
- Hidden Power [Fire]

Mamoswine @ Life Orb / Choice Band
Ability: Thick Fat
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Earthquake
- Icicle Crash
- Ice Shard
- Superpower / Knock Off

Kyurem-Black @ Choice Scarf
Ability: Teravolt
EVs: 252 Atk / 4 SpA / 252 Spe
Naive Nature
- Outrage
- Fusion Bolt
- Iron Head / Earth Power
- Ice Beam


This core features Lapras and Mamoswine as the respective special and physical wallbreakers along with Choice Scarf Kyurem-Black to clean late-game. For Lapras, the 176 EVs in Speed are used to outspeed max Speed Azumarill to make sure it can be KOed by Freeze-Dry. The set itself is pretty standard, as is Mamoswine's. Life Orb can be ran for the versatility, but Choice Band gives you a bigger power increase. Superpower is mainly to hit Heatran and Ferrothorn, but Knock Off can also be nice for removing Chansey and Porygon2's Eviolites, as well as being able to KO Jellicent. For the Kyurem-Black, Iron Head is pretty important for KOing Mega Diancie, but Earth Power is a decent alternative for doing good damage against Heatran and Excadrill.



Alolan Ninetales can set up Aurora Veil for the core while also being able to cripple things with Encore.



Piloswine can set up Stealth Rock for the core while also being able to consistently switch into Heatran and Nihilego. It additionally does some phazing with Roar.



Avalugg can remove hazards for the core while also switching into Choice Scarf Excadrill, Jirachi, and Infernape. It can also phase things out with Roar.




Scarfed Fighting types give the core a ton of trouble, since Kyurem-Black can't really outspeed either of these threats.



Offensive Mega Scizor variants are easily the most threatening, since they can outspeed and KO Lapras with a +2 Superpower. It's pretty much unavoidable for Ice to have a rough time with this thing.




Offensive Ice Core


Ninetales-Alola @ Light Clay
Ability: Snow Warning
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Aurora Veil
- Freeze-Dry
- Moonblast
- Encore

Sandslash-Alola @ Life Orb
Ability: Slush Rush
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Icicle Crash
- Iron Head
- Earthquake
- Swords Dance / Rapid Spin

Weavile @ Life Orb
Ability: Pressure
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Icicle Crash
- Ice Shard
- Knock Off
- Pursuit / Low Kick


With Fairy and Psychic being the best types in the current metagame, this offensive core is amazing on Ice teams. For Alolan Ninetales, the set is pretty standard, but you can choose to run Icy Rock over Light Clay if you want to give Alolan Sandslash more sweeping turns. However, Aurora Veil does do a nice job of letting it set up safely with Swords Dance. But Rapid Spin can be ran on more HO teams that don't carry Avalugg when you need hazard removal. As for Weavile, Low Kick can be ran over Pursuit if you're looking to hit Heatran and Tyranitar, but Pursuit is really nice for dealing with Victini and Latios, as well as Alolan Marowak to keep it from getting up Stealth Rock later. Overall, the core is meant to do nicely against offense, but will struggle rather heavily against more balanced types.



Mamoswine is easily the type's best Stealth Rocker, which greatly helps the core with cleaning. It can also serve as a nice blanket check with Focus Sash and Endeavor+Ice Shard.



Kyurem-Black can support the core with its amazing wallbreaking, being able to break through Toxapex, Mega Venusaur, and Skarmory. It also has good enough bulk to switch into some weaker Fire type attacks from Torkoal and Heatran.



Avalugg can serve as a bulkier Rapid Spinner to allow Alolan Sandslash to always run Swords Dance. It can also switch into Scarf Terrakion and Infernape, which severely threaten the core.



Lapras and Walrein help the core by checking Mega Scizor, which is easily one of the biggest threats to any Ice team. Lapras can also check Water types like Belly Drum Azumarill and Toxapex, while Walrein can switch into Fire type attacks quite easily thanks to its great bulk and access to Thick Fat.




Just like with the previous core, Scarfed Fighting types are an extreme pain to deal with, outspeeding everything on the core and KOing with either their Fighting STAB or their respective secondary STABs.



Pretty self-explanatory tbh. Mega Scizor can just set up and tear through the core. Despite Alolan Sandslash taking a Bullet Punch, it can't do anything notable back unless it has a Swords Dance boost, and even then it's unable to KO it.



As you may imagine, bulky Water types are a serious issue for the core. The core just gets stalled out by Vincune, even with Alolan Ninetales's Encore, and Toxapex can be a serious issue between Scald burns and Regen recovery.
