Hi
EleoOcelot, here is the Gmoltres Dark team you requested!
Galarian Moltres Hazard Stack Offense
https://pokepast.es/c6aafc7d4189224d
Gmolt's main role on Dark is that it's a great setup sweeper that has defensive utility as well, giving it a solid role on offensive teams. The main utility comes from its bulky special defense stat combined with its Flying typing, the latter giving it a neutrality to Bug and Fighting type moves that Dark teams traditionally struggle with as well as a Ground immunity for Pokemon like Overqwil, Alolan Muk, and Kingambit. With its high special bulk, its able to live weaker super effective attacks such as Enamorus's Moonblast and OHKO it with Hurricane in combination with Berserk's ability to boost its special attack automatically. With hazards and a combination of other offensive breakers, a well played Gmoltres can do considerable damage to a lot of different types, with the main examples being against balanced teams such as Water, Flying, Poison, and Ground. In order to build around GMoltres, you'd typically include a lot of the common Pokemon found on offensive Dark teams. You can use Weakness Policy if you'd like, but it's rather niche and situational compared to items like Heavy Duty Boots, Lum Berry mor Leftovers. On this type I found hazard stacking especially reliable at breaking in conjunction with GMoltres, so I included that. The Hydreigon and Overqwil sets are designed to get up and keep hazards on the field so GMoltres and other breakers in Kingambit and Chien-pao can punch holes. Without Sableye, it is extremely easy to remove hazards through Rapid Spin and many setup sweepers like Keldeo and Volcarona would punch through the team, so it fulfills a crucial role on the type. Usually, you'd run Recover on it, but it wants all 4 moves here and it's probably not lasting super long on hyper offense anyways. Double status is extremely good for crippling just about anything besides Dark Pokemon and Gliscor and having Thunder Wave in particular is great for things like Iron Valiant, Flutter Mane, Gouging Fire, and Enamorus.
Focus Sash Hydreigon is an interesting set that I've been messing around with recently that lets you get up Stealth Rock pretty liberally against a lot of types, mainly noting Flying. Hydreigon in general is really good on Dark because Dragon offers a lot of defensive utility as a typing since it can take Electric, Grass, Water and Fire attacks, compressing a multitude of roles onto one slot. As for the other hazard setter Overqwil, it's specially defensive to switch into Choice Scarf Enamorus, Iron Valiant, and Flutter Mane while Intimidate helps its physical bulk. The Kingambit's speed EVs allow it to outpace Iron Valiant if Sableye paralyzes it and no speed Heatran.
Overall this team should be pretty easy to pilot on ladder since it's mainly hazard offense hazard stack. Let me know if you have any questions regarding it!
