CROCUNE
https://pokepast.es/4006e6eed5240d75
This team is build around an underated threat of crocune and around the every annoying core of lop and kyurem.
Don't let this mon get any free switch ins as the only realiable way of killing this is to revenge with lop. Most of the time the chomp won't set up easily because every mon can at least annoy it.
This mon is a really terrible matchup as there're not great pivots and you just have to hope you have rocks up and get the para with clef.
You have ferro to pivot on grassy glide and wood hammer but if it has superpower your in trouble. At worst you make kyurem boots to pivot in on it and switch into a fighting resist.

This team is build around an underated threat of crocune and around the every annoying core of lop and kyurem.
I started off with Suicune with the first version being built around vincune but I then realized crocune was way better for setting up multiple times throughout the match. The tech of this set is that it's waterium z in order to get some more damage off of threats at plus one weakeaning mons that can take a plus one scald. I decided that I needed a mon to break through grass types and be able to resist electric attacks so I brought sub kyurem. Kyurem aides suicune in annoying blissey/pex through the match to get them into range of waterium z. With cune and kyurem I decided I needed some great speed control and who else can do that better than mega lopunny forming an amazing core with kyurem. I wanted my defensive core to have some variation of hazard stack so I used ferro to patch up the ash gren matchup and clef to counter other annoying mons. Then Gliscor rounds off the team with being the primary tran check and a volt switch blocker. edit: lol I didn't realize this team doesn't have defog, you can put defog on gliscor but I like the pressure that sd gliscor puts onto builds to break pex and grasses that don't resist ground.

From the moment I opened up the teambuilder I knew I had to use this core. Electric+Garchomp+Ash Gren is a truly terrifying offensive core that threatens just about every playstyle and team structure sans the hardest of Stalls, and Specs Koko is the best Electric rn imo. In terms of sets, I've chosen to go with double pivot move Koko since I want to guaratee the pivot into Chomp/Gren and also locking into HP lce loses far too much momentum for this kind of team. The Chomp set is pretty standard, as is the Gren set, albeit you could absolutely go U-turn>Spikes for even more momentum but this core with Spikes up is truly terrifying, especially if you slot Knock on Scizor > U-turn
Scizor was the natural next addition to this team, not only because it is an incredibly partner for ChompGren, but also because it shores up many defensive holes the team had vs stuff like Kyurem, Rillaboom, Kartana, and Lopunny and can also act as a downright nasty wincon once the prior three mons blow through its checks/counters. The spread and set is pretty standard but you can go Knock>Turn if you slot Turn on Gren but you give up hella momentum
Now this is where the heat truly lies. Mantine may seem like an odd pick, but it fits perfectly on this team thanks to its ability to hard check Gren, Zard-Y, Tran, and Rain and provide Defog all in a single slot. The given spread turns regular Gren Dark Pulse into a 4HKO and the rest is dumped into defense to help it tank hits from other shit. The given moves let it Defog while also being annoying as shit with Scald/Toxic. You can slot Ice Beam or Haze last if you want to annoy specific mons (Gliscor/Scizor, though you annoy that pretty hard already).
Rounding out the team is CM Flamethrower Clefable, a set that I realized fit perfectly on the team thanks to it serving as a Dragon immunity, Dark resist, backup Lop check, and wincon all in one slot. Not only that, but the team up to this point struggled with bulky Grasses such as Ferrothorn, Amoonguss, and Tang, and even Steels such as Corv and Scizor could prove troublesome, so CM Flamethrower Clef was the perfect way to lure those mons and eliminate them for the rest of the team. Set and spread are standard otherwise.
Uhhhh if you lose Chomp and somehow miss every Pump it can be annoying ig but even then you should not lose to it.
First 2 mons are the standard suicide Rocks lead and Screens setter consecutively. Drill is the best suicide lead atm thanks to its ability to act as a hazard setter, hazard removal, and makeshift speed control all in one. Not only that, but its ability to get up and keep up rocks vs pretty much any archetype makes it an invaluable asset to the team. Meanwhile, Grimmsnarl is the best screen setter atm imo thanks to Prankster and the ability to act as a makeshift Mega Lop and Gren check, and even act as a secondary way to keep up hazards thanks to Taunt. Sets and spreads are standard af
Usually I hate building around this mon but the moment I saw its SD Scale Shot set in action (on Screens no less) I knew I had to have it here. +2 Adamant M-Chomp hits like a fucking dumptruck and is scary enough, but with Scale Shot, it turns from a terrifying wallbreaker into a terrifying sweeper that's deceptively hard to revenge kill, especially behind screens. Moves are pretty self explanatory, with Fire Fang rounding out the movepool to hit Corvs. Adamant>Jolly for raw power
Manaphy is a rather unusual pick, but a damn potent one. Thanks to the given spread which emphasizes bulk alongside Screens support, it's insanely easy for Manaphy to get to +6 and start crushing teams. The set is one that took me a while to decide on. The spread is one taken from rain teams that lets it creep Timid Zone and Defensive Zapdos. You can however, creep up to Modest Heatran and Tapu Fini if you wish. In terms of moves, Tail Glow and Surf are pretty standard, Ice Beam is to hit Grasses, but the last move is where things get interesting. I've gone with Energy Ball to improve the Stall MU and beat Gastrodon/Fini, but you can also go with Psychic to murder Pex and Mega Venu, HP Fire to murder Ferrothorn/Kartana, or even Rain Dance to make it more self sufficient. In terms of item, you can also do quite a few things here. I've elected to go Lum before it lets me absorb T-Waves/Toxics/Scalds with relative impunity and set up in the face of stuff that would otherwise stop my sweep. However, Wacan Berry is an option to fuck over Electric types, Rindo is an option if you want to bait in Rillabooms/Kartanas/Ferrothorns and destroy them. Finally, Quick Claw is an option if you truly hate your opponent and the very concept of fairness, and if you run it with enough speed to creep Rillaboom, you can become a true degenerate. Manaphy is easily the most flexible member of the team in terms of well, everything and you can truly change it to fit the team's needs.
The final team member is my favorite mon on HO: Double Soul Kommo-o. Usually regarded as a MU fish, Double Soul Kommo-o works incredibly well on this team not only due to its ability to stomach hits from and set up on the likes of Heatran, Rillaboom, Ash Gren, Zapdos, and others, but also its ability to abuse the support given by Chomp/Volc/Manaphy insofar as their ability to pressure and eliminate the Fairies and Bulky Waters it despises, finding it especially easy to set up fully once the former is eliminated. Double Soul Kommo-o functions less as something you can go into turn 3 and win with and more something that just cleans up once the rest of the team has punched through its checks/counters/worn them down. The set and spread are pretty standard, with the given moves giving it the best coverage possible.
Uhhh if screens aren't up I guess this just kills everything.
One thing that I learnt when piloting Garchomp-Mega is that, while on paper he's a sweeper, he often comes in on necessity to check Pokemon like Heatran. Between hazards, tanking a few neutral hits, as well as status, the utopian case of Chomp sweeping a team is often never a reality: plus, he takes time to get going between Scale Shot and Swords Dance separately boosting its stats. Healing Wish Jirachi gives Chomp increased longevity and multiple chances to threaten the opposing team, while also checking various Fairy-types like Tapu Lele. In exchange Chomp can help versus various Fire-types that would threaten out Jirachi. We also stan momentum in this house.
This would leave a hole versus bulky Waters such as Slowbro, so Serperior was a natural fit here, especially since Glare can mediate Chomp's speed issues. Serperior is also naturally another Pokemon that loves receiving help from Jirachi and having another chance to snowball Leaf Storms in the opponent's face. It can also to a smaller extent check physically defensive Ground-types such as Hippowdon that would annoy Chomp and would make Jirachi useless.
and 
Moltres is role compression, providing a Heatran switchin along with Kommo-o. Fitting natural Fire coverage for steels like Scizor, Ferrothorn is a plus and it can spread helpful burns. EVed to avoid 2HKO from Zard Y Weather Ball and outspeed Modest Zone.
Lando-T is also a good bit of speed control. Feel free to mix up the moves, I opted for HP Ice + Stone Edge Lando since Jirachi can generally handle Mega Latias. I also think Explosion is nice to revenge things like +1 Kommo-o.
the choice band axel variant has a good matchup on 5/6 mons, will likely claim a kill but nothing gives it free entry.
Heatran is the team's rocker and is frankly the best possible partner for this Koko set since in return for taking on the bulky Waters and Grounds that Tran hates so much, Tran threatens and even eliminates the bulky Grasses that Koko can't touch. The set and spread is pretty normal, albeit I used just a bit more speed to get the jump on Tran creepers
Rocky Helmet Tangrowth is said mon, not only serving as a solid check to SD Grounds like Lando (barring Fly-Z), Gliscor, and Garchomp, but also serving as an excellent pivot into Lopunny, Kartana, Ferrothorn, and Excadrill. HP Ice > Fire better targets Grounds though if you want to just mess up Ferros, Scizor,s and Karts that much harder you can go HP Fire here and go HP Ice on Lando, though that makes Gliscor a bit trickier imo. The last move here is Rock Slide since the powders are rendered ineffectual by double terrain, EQ seemed kind of redundant, and Rock Slide patches up the otherwise awful Zard-Y and Volcarona matchups
Fini rounds out the team as the team's defogger, Ash Gren check, Heatran check, and general annoyer of slow, fat shit. Set and spread are pretty standard, and its ability to just annoy stuff like Clef, Corv, and the Slowtwins is greatly appreciated
