In the process of teambuilding, a strong core is a key component to make the process easier, and give the team a good back bone. This thread will be used for the purpose of showing off some great cores! With SPL and all these other tournaments about to start, feel free to post some cores that you've used or seen while building or watching tour games. You may like this thread to show off some cool mons that you put together, or just to steal some ideas for your own teambuilding, whatever works for you.
So what constitutes a good core?
An offensive core utilizes two Pokemon that are able to work together to break through whatever Pokemon the opponent is using, allowing the rest of the team to support those two Pokemon as the focal point. A good defensive core is a combination of two Pokemon that are able to switch into or check a good chunk of the offensive Pokemon in the meta, serving as the backbone of the team. Balanced cores a mix of these definitions, being able to check almost all Pokemon while still carrying some type of offensive presence.
Please label your core with the tag 'Hyper Offensive,' 'Bulky Offensive,' 'Balanced,' or 'Stall' in bold so that I don't have to try and decide where your core goes.
Hyper Offense
+
I've been using this core a lot in this gen, Shuckle is a good way to set up Sticky Webs and Stealth Rock, can beat Defog users without difficulty using Encore on the defog and toxic after. The good thing about this core is the support Sticky Webs gives, Lunala is a powerful Pokemon and I tested Choice Specs on this jewel, giving good scores, Moongeist Beam Specs KO most of the metagame and Sticky Webs helps here dropping opposing pokemons speed, with choice specs it hits hard against Blissey, Arceus-Dark, Primal-Groudon, and more stuff, also this thing avoids Rapid Spin from Excadrill and defog from Giratina-Origin (Non Shadow Sneak), helps a lot, this core can be used with Z-Splash Solgaleo too, its a nice way to do a clean sweep under webs, have fun.
+
Pretty basic Psyspam core with Tapu Lele + Deoxys-Attack. Tapu Lele sets up Psychic Terrain while Deoxys-Attack abuses the terrain being up. The whole idea of this core is to drop boosted Psycho boosts, Psychics and Psyshocks, in addition to being protected against priority allowing Deoxys-Attack to pick up an easy kill even VS the likes of Yveltal, SD Arceus forms, Giratina-Origin, Mega Lucario, Rayquaza, and Mega Kangaskhan. EV spread on Tapu Lele enables it to outpace 252+ Primal Groudon in addition to surviving a Shadow Claw from Jolly Life Orb Arceus while maximizing its Special Attack stat. Psychic and Moonblast are STAB. Psychic instead of Psyshock on Tapu Lele since it enables it to hit Xerneas, Primal- Groudon and Arceus-Water harder while Moonblast allows it to hit the likes of Yveltal, Tyranitar, and Mega Sableye who would wall Tapu Lele otherwise. Taunt allows it to prevent Xerneas from clicking Geomancy on it and potentially sweeping while also being useful in preventing Arceus from getting rid of SR. It also forces some mons out so it can take advantage of that and fire off a Psychic or Shattered Psyche to hit something really hard. Psychic Terrain allows it to set the terrain again if it runs out while Shadow Ball allows it to deal significant damage to Solgaleo and Tapu Lele, while severely damaging Lunala.
Rash nature allows Deoxys-Attack to capitalize on it's special attacking prowess. Superpower allows it to hit Tyranitar since Deoxs-Attack would get Pursuit trapped otherwise. Psyshock allows it to pick off a weakened mon without resorting to the use of Psycho Boost. Psycho Boost is a nuke especially with terrain active as it is able to OHKO a lot of mons, Ho-Oh for example. Knock Off provides general utility, screwing over something that heavily relies on its item like Chansey while hitting Lugia, Aegislash, Solgaleo and Lunala. Pursuit allows it to trap THE TRAP GOD Mega-Gengar. Ice Beam allows it to decimate Mega-Salamence, Zygarde-Complete and hits Yveltal.
These types of builds tend to be matchup reliant and is somewhat gimmicky if not built properly. I'd personally run Terrain Extender instead of Psychium Z as it helps stave off priority attacks for a longer duration since priority can be annoying especially considering the fact that 5 turns go by very quick. This makes the matchup vs SD Arceus and the aforementioned priority users better. Sure Shattered Psyche is nice as it hits something really hard but yeah Deoxys-Attack has more turns to abuse.
+
Pretty basic offensive combo. Mega Lucario is really good at murdering stuff, but bulky Ghost-types and Zygarde-Complete are a couple things it can struggle against. Yveltal takes care of those obstacles nicely, and can make use of U-turn to get Mega Lucario into battle against things it can set up safely on like Tyranitar and Blissey. Mega Lucario makes a nice offensive check to Fairy-types and Arceus-Rock/Dark in return. Neither of these can switch into Xerneas though, so a Fairy-type switch-in such as Primal Groudon is recommended. A late-game cleaner such EKiller or Xerneas is also nice here since this core does a good job of softening most defensive cores.
+
This core its pretty good and old, the first time this core appeared was in XY times, becoming famous thanks to Dice's team, but the term "Old" doesn't make it bad, it is actually good on this metagame vs some Hyper Offense teams thanks to Forretress + Taunt Aerodactyl, being able to set up hazzards and thanks to Sturdy, Red Card its a Item that helps vs Baton Pass, also helps vs Xerneas boosted, Aerodactyl Mega can set up Stealth Rocks in the field and can switch in one time vs Ho-Oh or Salamence-Mega on the roost, Taunt its for some walls and stuff that try to Thunder Wave, Rock Tomb is used to drop speed vs faster stuff, making easy to revenge kill, Stone Edge its a better option if u want damage with Aerodactyl and take down Salamence, Pursuit its a choice to stop Lunala non-scarf from switch and Deoxys-Attack non-full speed, Earthquake its another choice to hit hard Primal Groudon and Solgaleo, pretty useful core that has been used on SPL Match Astounded vs Sin Victim.

this is the best core suited to utilizing cloyster in the curent metagame, which unlike forretress is ranked and actually does something during games. simple premise, set up spikes with cloyster while using taunt aerodactyl to prevent defog or vice versa - set up rocks with aerodactyl and applying hard offensive pressure to prevent defog. team options include ekiller, mega gengar, ghostceus, xerneas, rp pdon, and lunala.
On the surface this just looks like two of the strongest sweepers in the tier slapped together, but they actually have a surprising amount of synergy together. Mega Lucario and physical RP Groudon share a lot of similar checks, but mixed RP Groudon can lure a number of those such as Mega Salamence and Landorus-Therian to make it easier for Luke to sweep later on. Many RP Groudon checks such as Support Arceus are setup fodder for Mega Luke. More importantly, the two of them cover each other's status weaknesses, with P-don absorbing T-Wave and Will-o-Wisp for Luke, and Luke returning the favour by taking Toxic for P-don. Just make sure to pack a good Zygarde-C answer because even with Hidden Power Ice, the fat raid boss dragon can take a beating from these two all day long.

Pretty good offensive core that can fit on numerous types of builds but usually ends up looking like bulky offense. The goal is to remove xerneas checks with duggy using arena trap. A ton of checks like Pdon, Solgaleo, Magearna, and Toxapex. It can power through them with z eq pretty easily allowing xern to sweep. Dugtrio can also remove weakened mons obviously kinda like how mgar can work but it's a lot weaker so these mons need to be close to zero. A sash set can also be used to utilize trapping then suiciding with memento for xern to setup easier or perhaps setting up sr. The moveset on xerneas is pretty self explanatory. Thunder and hp ground provide the best coverage in sumo so far. A resttalk set can be used but since the goal of this set is to remove checks and go for an easy setup and sweep I think coverage is a lot better.
+
A really dangerous core if it manages to get going. Mega Scizor is really good at baiting Fire-types such as Primal Groudon and Ho-Oh to switch-in, which you can exploit with U-turn to get Primal Kyogre in for a free attack against the opponent's team. Against a team that relies mostly on Primal Groudon to check Primal Kyogre, this can be quite advantageous. Any Primal Kyogre set works in this core, but CM + 3 Atks is the most fun set so I picked that one. Swords Dance + Roost also lets Mega Scizor take on more defensive Primal Kyogre checks such as Ferrothorn and Blissey if necessary. This core will need a mon that can actually switch into Primal Groudon if something goes wrong though, so Giratina-O makes a good partner here.
Very self-explanatory. P Don checks a bunch of threats like usual, and Kyogre covers most things that threaten Primal Groudon. Defensive Donner just had so much splashability, while you can change the Kyogre set for how offensive/defensive your team is. EVs on the offensive Ogre can change depending how much bulk you want on (can go full Spe or full HP or anywhere in between depending on how you play). You'll note that this core itself is still weak to opposing Primal Groudons, which is why you'd still have to patch that weakness up, but that's very easy. You can base whole bunch of teams around as your defensive backbone depending on how offensive/defensive you want to be.
For bulky offense you can easily go: PDon + POgre (offensive set) + Scarf Lando-T or Mega Mence -> 3 other sweepers
For balance you can easily go: PDon + POgre + Gira-O -> splashable mon (eg Supportceus) + 2 other attackers or whatever
Great thing about this core is how versatile it is. I've even put it onto bordering-HO type offense teams and it's worked beautifully. All you need is your choice of Ground-resist, then you can pretty run whatever the hell you want.
+
This core is primarily based on providing lunala, whether is scarf, specs, or anything else, and giving it a much needed dark/ghost resist. Lunala does most of the work due to its ability to punish most mons with it's coverage but having a check to mons like ekiller, SD pdon, and more is nice in itself. The specific sets I chose deal with a wide chunk of the mons in the tier barring speedy threats (which shouldn't be a problem if you support the core well enough). Primarily this core allows you to really pressure those bulkier based team while also have a check to most physical mons on an offensive based team. If you are worried about getting outsped by mons like deo, then just change luna to scarf and you have better means of dealing with offense. I does of course have weaknesses, but, again, as long as you have the proper support mons to back up the core, you're in a solid position
simple combo, dialga is able to check common rp pdon checks such as mence and waterceus while also setting up rocks, freeing up pdon's moveslot for a team. as we all know, pdon is a vicious sweeper and can be dangerous in any game. mixed rock polish pdon is also an option for this core as is toxic or roar somewhere on dialga. partners include stuff that can handle opposing pdon such as groundceus and a secondary check to xerneas such as ho oh. also get a groundceus check o,o
Simple concept. Ekiller struggles to deal with ghost-types, which Y-God can come into with impunity and proceed to get off chip damage to ease the late game Arceus sweep. Yveltal can also Knock Off to get rid of Leftovers, Choice Scarfs etc that can annoy Arceus. While Arceus doesn't offer Yveltal much in terms of team support, it helps finish off fast sweepers such as Xerneas who can easily set up on Yveltal. The utility of two STAB priority options between them can get you out of many desperate situations. Both can keep themselves relatively healthy between Recover and Oblivion Wing, though it is recommended to keep around a status absorber as Toxic will take its toll.
Balance
+
This combo is pretty dope. Ferrothorn and Zygarde can handle each of their respective checks pretty decently (though Taunt is a problem for both in a sense), and they both form a nice parashuffling core if Glare is used. Spreading paralysis that can catch Ground-types like RP PDon along with large resid with Spikes + DTail can be pretty potent for bulkier wallbreakers like LO ygod and such. The damage from Spikes can actually help out Zygarde against the frailer things it checks (MLuke can't really pressure Zyg pre-Power Construct if 3 layers of Spikes are up and/or do you really want a parad MLuke). You also really annoy support Arc formes with para so it's harder for them to Defog or just do their job since Ferro can just switch in on most just fine. Granted Xern isn't fully covered so adding PDon is really nice with Leech Seed recovery and a potential SR setter, and the core doesn't really do much against most Psychic-types so preparing for that is a must. Overall this is a really nice basis for a core that doesn't just sit there and sponge damage like a bunch of non-Ho-Oh balance cores and can be really flexible for what additional team members it can have since everyone likes Spikes, Leech Seed and yellow magic.
+
Buzzwole and Arceus-Water cover most physical threats together, barring stuff like SD PDon with Fire Punch and Zekrom. PDon doesn't usually use Fire-type coverage on its SD sets which takes a lot of pressure off Arceus-Water, and in general Buzzwole blends most SD Grounds into protein shakes before hitting the gym to work on his quads. In return, Arceus-Water takes care of a lot of physically oriented Flying-types like Ho-Oh and Mega Salamence. This core has issues with things like Xerneas, Yveltal, strong Psychic-types, and offensive Primal Kyogre so partners such as Primal Groudon, Yveltal, and Magearna/Klefki work well alongside here, especially since this core is rock-solid against Ground-types.
+
Surprised no one has posted this yet as I've seen it being used a lot on the ladder in the past few days. Magearna provides a switch-in for basically everything that stops Zygarde-C from setting up. It's probably the best Xerneas check out there with Heart Swap and its typing also lets it beat Taunt Yvetal which shuts down this Zygarde set. Additionally, it walls Iceceus, Waterceus and POgre which often carry Ice-type coverage, though it can't do much in return and has to pivot out into a check with it's slow Volt Switch. Meanwhile, Zygarde-C sets up all over Magearna's biggest counter in Primal Groudon, as well as bulkier mons which Magearna really struggles to break through, such as Ferrothorn and Toxapex.
Very self-explanatory. P Don checks a bunch of threats like usual, and Kyogre covers most things that threaten Primal Groudon. Defensive Donner just had so much splashability, while you can change the Kyogre set for how offensive/defensive your team is. EVs on the offensive Ogre can change depending how much bulk you want on (can go full Spe or full HP or anywhere in between depending on how you play). You'll note that this core itself is still weak to opposing Primal Groudons, which is why you'd still have to patch that weakness up, but that's very easy. You can base whole bunch of teams around as your defensive backbone depending on how offensive/defensive you want to be.
For bulky offense you can easily go: PDon + POgre (offensive set) + Scarf Lando-T or Mega Mence -> 3 other sweepers
For balance you can easily go: PDon + POgre + Gira-O -> splashable mon (eg Supportceus) + 2 other attackers or whatever
Great thing about this core is how versatile it is. I've even put it onto bordering-HO type offense teams and it's worked beautifully. All you need is your choice of Ground-resist, then you can pretty run whatever the hell you want.

This is another Buzzwole defensive core that I've been testing and it's actually pretty nice. Rather than focusing on the full stop of physical attackers like Buzzwole + Arc-Water, the addition of Alolan Muk covers a lot more holes with hard checks when teambuilding. Alolan Muk struggles greatly with most Ground-types and Mega Lucario, which Buzzwole can take care of quite handily. Buzzwole primarily struggles with most special attackers like Xerneas and general Psychics and Ghosts, which Alolan Muk eats up most of the time. Essentially what this core does is take care of common wallbreakers quite well, mainly SD Primal Groudon, Tapu Lele cores, Darkrai, Deoxys-A, Lunala, Mega Gengar and Mega Lucario (and to some extent Xerneas and Yveltal but pls don't use Muk as your only Xern check). That can take a lot of strain off other team members since one of the core members has reliable recovery while the other can Pursuit trap important targets. However, this core doesn't cover absolutely everything, with Xerneas, Primal Kyogre, and Mega Salamence being left out of this core's capabilities. Primal Groudon is always a good team member to handle Primal Kyogre and Xerneas, and Arceus-Rock or Arceus-Fairy can deal with Salamence. Giratina-O and Ferrothorn are also notable teammates to provide Defog support or Leech Seed and Spikes to supplement Alolan Muk's average offensive presence and lack of recovery.
A really solid defensive backbone for the new meta, this is capable of dealing expertly with strong ground types like groudon, zygarde-c and arceus-g while also taking care of the promiment ghost type threats known as gengar and lunala. They support one another very well; muk can take care of the ghost types that threaten slobro while slowbro can take care of the grounds. Not only can they support eachother well, they support other teammates very effectively. Primal groudon appreciates slowbro's ability to wall zygarde-c and ho-oh and muk's ability to trap lugia. Arceus steel/poison share this appreciation, and they are options to consider using with this core as it needs a proper xerneas check. Most other teammates have an easier time when gengar/lunala as well as lugia is off the field thanks to muk, especially defensive teams or hazard-oriented teams. This core is not without weakness, arceus-w and primal kyogre dont care about either of the two, while xerneas is still a large threat without clear smog on muk. Overall it is one of the best defensive backbones of the meta.
Ho-oh is one of the best status spreaders in the tier and between Sacred Fire and Toxic, you can get a status condition on pretty much any common Ho-oh switch in. This allows Mega Gengar to trap and annihilate many of them with Hex, such as support Arceus and Lugia. It also has the capacity to traps many Stealth Rock setters to allow Ho-oh to switch in freely as the game progresses. In return, Ho-oh is immune to the plethora of ground-type coverage moves aimed at Gengar and although it can't beat powerful ground types like Primal Groudon and Arceus Ground on its own, it can put them on life support via Toxic. Defog/Rapid Spin support is mandatory with the inclusion of Ho-oh.
About as solid as it gets when it comes to defensive cores on balance.
Primal Groudon takes care of pretty much anything that Celesteela doesn't like to deal with, bar fast Primal Groudon with a fire move.
Another one that I am fond of myself.
Trout used it in SPL as well.
Calm Mind + Judgement gives you something to abuse the amazing offensive typing that is Dark, while Magearna keeps the things that Arceus Dark doesn't like to deal with (mainly Xerneas) at bay.
Stall
+
This is a combination that is very easy to use and implement into a stall team. Zygarde is your physical wall that can take care of threats such as Mence, Pdon, and Lucario. Blissey on the other hand, handles specially offensive Pokemon like Pogre, Xerneas, and CM Arceus formes. Despite the fact that this core alone can check most of the metagame, it is still heavily threatened by Deo-A and Lunala (if it has Psyshock/Ice Beam that is) so some type of Pursuit trapper would help out immensely when using these 2 mons.
Physically-defensive Ho-Oh is a double-sided wall which can counter many Pokémon in the Übers metagame, and its longevity is further augmented by its insane healing potential thanks to Recover and Regenerator. Giratina makes an excellent Defog user thanks to its Pressure Ability, which allows it to outstall the opponent's Stealth Rock in most cases. As such, it synergizes extremely well with Ho-Oh, which really appreciates having Stealth Rock off its side of the field. With its incredibly huge physical bulk, it can take powerful physical attacks aimed at Ho-Oh and Clefable, while its resistance to Water also allows it to take attacks of such a type aimed at Ho-Oh somewhat. In turn, Ho-Oh, with its high Special Defense, can take super effective special attacks aimed at Giratina, such as Moongeist Beams, Moonblasts, Ice Beams and Dark Pulses. Clefable's immunity and resistance to Dragon- and Dark-type attacks respectively aimed at Giratina is awesome. Heal Bell can wake Giratina up from its sleep when it uses Rest, and cure Ho-Oh of undesirable status effects such as Toxic. Finally, with its Unaware Ability, Clefable can counter most Calm Mind or Swords Dance Arceus Formes, as well as Geomancy Xerneas.
Chansey, as we all know, is extremely reliable when dealing with the majority of the special attackers in the tier. It can cover pretty much all of your team's specially oriented weaknesses, but struggles with both physical attackers and Lunala/Gengar. Arceus-Ground covers the former by being able to provide a solid check to Primal Groudon, Mence and other physical attackers while still being able to Defog and cripple switch-ins with Toxic. Chansey can, in return, check special attackers that might give Arceus-Ground problems and its ability to serve as a cleric further aids Arceus-Ground by getting rid of annoying status conditions that could otherwise trouble it. With Arceus-Ground being able to check Primal Groudon and somewhat check threats like Lucario, Muk-A has a lot more breathing room to work with and can do what it does best, that being pursuit trapping (Gengar, Lunala, Deoxys, etc.) and overall checking most of the Ghost and Psychic (and sometimes even Dark) type Pokemon in the tier for Chansey. The core is overall extremely balanced and reliable, but it still struggles with some Pokemon, such as some Steel-types (Celesteela, Ferrothorn, Skarmory, etc.) and can't break down some teams on it's own. Despite those hindrances, it's an extremely effective starting point for stall teams, being able to patch up a large number of holes and lay down a solid foundation.
If anyone wants to add/change anything to this, feel free to do so.

Landorus Therian with Smeargle its and old and interesting core, Old because this core was used in ORAS on Sticky Webs teams, the core have a variation that can be Landorus-T + Shuckle, but I prefer this because Dragonium Z its used, Landorus-T Dragonium Z its a really interesting set because Webs hate Giratina-Origin and defensive stuff, at the moment Outrage Z Adamant brings down Giratina-Origin, Salamence Mega and Zygarde at 100% (Not Complete Form), this is helpful for Webs, Smeargle have that moveset because testing I found that Substitute set up users were a dangerous threat and Roar was the way to stop them, also helps vs Excadrill or others Rapid Spin users.

The main function of this core is to use Yveltal to U-Turn on things that would switch in and wall it and then go to mega gengar and trap them. Things like Xerneas, Arceus-Fairy, Ferrothorn, Celesteela, and Skarmory all don't like getting U-Turned on and can easily be exploited by this core. On a different note of what threats each pokemon checks, Mega Gengar helps to check Ekiller and most Fairy types while Yveltal helps clean up the weakness of most ghost and dark types checking things like Scarf Lunala, Ghostceus, and other Yveltal. This core heavily dislikes Ho-oh, so it would be wise to get some sort of way to break through ho-oh or cripple it. The core also isn't too solid vs certain bulky support Arceus, mainly Darkceus, Dragceus, and Waterceus since they can just toxic you and recover spam. Solid choices to support this core are strong physical attackers that don't mind having bulky steels gone or fairies. Two good examples are SD Primal Groudon and SD Groundceus, which both benefit either from steels being gone, fairies, or both and at the same time can also pressure support Arceus forms and Ho-oh.

Pretty good offensive core that can fit on numerous types of builds but usually ends up looking like bulky offense. The goal is to remove xerneas checks with duggy using arena trap. A ton of checks like Pdon, Solgaleo, Magearna, and Toxapex. It can power through them with z eq pretty easily allowing xern to sweep. Dugtrio can also remove weakened mons obviously kinda like how mgar can work but it's a lot weaker so these mons need to be close to zero. A sash set can also be used to utilize trapping then suiciding with memento for xern to setup easier or perhaps setting up sr. The moveset on xerneas is pretty self explanatory. Thunder and hp ground provide the best coverage in sumo so far. A resttalk set can be used but since the goal of this set is to remove checks and go for an easy setup and sweep I think coverage is a lot better.

For bulky offense you can easily go: PDon + POgre (offensive set) + Scarf Lando-T or Mega Mence -> 3 other sweepers
For balance you can easily go: PDon + POgre + Gira-O -> splashable mon (eg Supportceus) + 2 other attackers or whatever
Great thing about this core is how versatile it is. I've even put it onto bordering-HO type offense teams and it's worked beautifully. All you need is your choice of Ground-resist, then you can pretty run whatever the hell you want.

Trout used it in SPL as well.
Calm Mind + Judgement gives you something to abuse the amazing offensive typing that is Dark, while Magearna keeps the things that Arceus Dark doesn't like to deal with (mainly Xerneas) at bay.

Physically-defensive Ho-Oh is a double-sided wall which can counter many Pokémon in the Übers metagame, and its longevity is further augmented by its insane healing potential thanks to Recover and Regenerator. Giratina makes an excellent Defog user thanks to its Pressure Ability, which allows it to outstall the opponent's Stealth Rock in most cases. As such, it synergizes extremely well with Ho-Oh, which really appreciates having Stealth Rock off its side of the field. With its incredibly huge physical bulk, it can take powerful physical attacks aimed at Ho-Oh and Clefable, while its resistance to Water also allows it to take attacks of such a type aimed at Ho-Oh somewhat. In turn, Ho-Oh, with its high Special Defense, can take super effective special attacks aimed at Giratina, such as Moongeist Beams, Moonblasts, Ice Beams and Dark Pulses. Clefable's immunity and resistance to Dragon- and Dark-type attacks respectively aimed at Giratina is awesome. Heal Bell can wake Giratina up from its sleep when it uses Rest, and cure Ho-Oh of undesirable status effects such as Toxic. Finally, with its Unaware Ability, Clefable can counter most Calm Mind or Swords Dance Arceus Formes, as well as Geomancy Xerneas.

Chansey, as we all know, is extremely reliable when dealing with the majority of the special attackers in the tier. It can cover pretty much all of your team's specially oriented weaknesses, but struggles with both physical attackers and Lunala/Gengar. Arceus-Ground covers the former by being able to provide a solid check to Primal Groudon, Mence and other physical attackers while still being able to Defog and cripple switch-ins with Toxic. Chansey can, in return, check special attackers that might give Arceus-Ground problems and its ability to serve as a cleric further aids Arceus-Ground by getting rid of annoying status conditions that could otherwise trouble it. With Arceus-Ground being able to check Primal Groudon and somewhat check threats like Lucario, Muk-A has a lot more breathing room to work with and can do what it does best, that being pursuit trapping (Gengar, Lunala, Deoxys, etc.) and overall checking most of the Ghost and Psychic (and sometimes even Dark) type Pokemon in the tier for Chansey. The core is overall extremely balanced and reliable, but it still struggles with some Pokemon, such as some Steel-types (Celesteela, Ferrothorn, Skarmory, etc.) and can't break down some teams on it's own. Despite those hindrances, it's an extremely effective starting point for stall teams, being able to patch up a large number of holes and lay down a solid foundation.
If anyone wants to add/change anything to this, feel free to do so.
