The Pokeballs catch rate in sword and shield is lower on average but they have been a defining item in every Pokemon game so far and Pokemon Sword and Shield are no different. There haven't really been any new Pokeballs added in the game but there are special Pokeballs found throughout the Galar region. T
Pokeballs have come so far that the Nintendo Switch even has a "Pokeball Controller" you can use for the console. This was introduced in Pokemon Let's Go: Eevee and Pikachu and you can still use this controller to get Mystery Gifts and catch Pokemon in-game.
There is also a "Ball Guy" in every Gym you go to and usually talking to him will give you free Pokeballs.
