A good team could be Pikachu for its popularity and electric type moves which are useful in many situations. Charizard as it's a powerful fire type. And Bulbasaur which can cover different types with its grass and poison attacks. These three are classic and can handle a lot in the story.
For a story - based pokemon team, I'd consider having Squirtle. It's a great starter with water type moves that can be very effective against fire types. Then, Eevee is a wonderful choice as it can evolve into different types depending on what your team needs during the story. Also, Lucario. It has a cool design and its fighting and steel type moves make it a strong contender in battles.
Well, in my opinion, a solid team for the Pokemon Shield story would be the following. Firstly, have a Zamazenta. It's a powerful Legendary Pokemon with great stats. Then, add a Centiskorch. It's a Fire - type with high attack power. Next, include a Grimmsnarl. It has good special attack and can be quite a tank. Also, consider a Duraludon. It's a Steel - type which is great for defense against many types. Finally, have a Mr. Rime for its ice - type moves and its unique look. This combination gives you a good mix of offense, defense, and different types to handle various situations in the story.
A good team could be Sprigatito, Fuecoco, Pawmi, Rookidee, Nacli, and Hoppip. Sprigatito has some useful grass - type moves early on. Fuecoco is a solid fire - type. Pawmi is an electric - type with decent power. Rookidee is a fast flying - type which can be very helpful in battles. Nacli is a rock - type that can take hits well. Hoppip is a grass - and flying - type that can be useful in different situations.
Well, when it comes to a good team for the story in Pokemon Sword, you can't go wrong with Zacian, the legendary of the game. Along with Zacian, having a team of Scorbunny (evolved into Cinderace) for its speed and firepower, Snorlax for its bulk and power, Lucario for its fighting and steel typing which is great against many opponents, Gardevoir for psychic support, and Flygon for its ground and flying type combination which helps in traversing different terrains and battles.
For the story mode in Pokemon Sword and Shield, Sobble, Grookey and Scorbunny are great starters. Sobble can turn into a powerful water - type, Grookey into a strong grass - type and Scorbunny into a fire - type. They can cover a wide range of types as they evolve.
A great team could be Greninja, Charizard, Sylveon, Lucario, Tyranitar, and Hawlucha. Greninja is fast and strong. Charizard has high attack power. Sylveon can be a good support. Lucario is a great all - rounder. Tyranitar is bulky and powerful. Hawlucha is quite agile in battles.
A great team could be Sprigatito, Fuecoco, and Quaxly as your starters. Add in Pawmi for its cute and useful Electric moves. Girafarig is also good for its Psychic abilities. And Maushold for its unique and powerful attacks. This combination gives you a mix of different types to handle various situations in the Pokemon Violet story.
A good team could be Cinderace, Inteleon, Corviknight, Hatterene, Toxtricity, and Dragapult. Cinderace is a strong Fire - type with great speed and attack. Inteleon is a reliable Water - type sniper. Corviknight is a tough Flying/Steel type that can take hits. Hatterene has strong special attack. Toxtricity offers unique Electric/Poison typing. Dragapult is a powerful Dragon/Ghost type with high speed.
Well, I'd say for the story in Pokemon Shield, you could go with Sobble, Grookey, and Scorbunny as your starters. Then add some like Duraludon which is a Steel / Dragon type and can handle a lot of different types. Also, Grimmsnarl, a Dark / Fairy type that's quite tough in battles. And Appletun, a Grass / Dragon type that has some useful moves and good bulk.
A good team could be Zacian, Rillaboom, Inteleon, Corviknight, Dragapult, and Toxtricity. Zacian is a very strong Legendary Pokemon. Rillaboom is a great Grass - type with powerful attacks. Inteleon is a reliable Water - type. Corviknight can provide good flying support. Dragapult is a fast and strong Dragon - type. Toxtricity can deal with different types of opponents with its dual - type nature.
A possible best Pokemon Sword team could be built around Duraludon. It's a steel - type with high defense and attack. Add Centiskorch for its fire - type power and long - range attacks. And Boltund, a speedy electric - type. Their story could be that they are on a quest to find the rarest Pokemon in Galar. They face many tough battles, but their combined strength and different types help them get through. For example, Duraludon can take on physical attackers, while Centiskorch burns down grass - types and Boltund zaps water - types.
