The Master Ball is a one-of-a-kind Poké Ball. Pokémon Sword and Shield. When you throw it, you have a 100% chance of capturing any Pokemon you hit. It's exceptionally rare, and because of catching a Pokemon, trainers seek it out to make sure they can always get the rarest encounters.
To get it into Pokémon Sword and Shield, you have to fight your way through the entire game. You don't beat the game just by getting all eight gym badges. You defeated by facing Battle Tower where you have to face Leon, the champion The Pokémon, whom you have seen throughout history. Take it, win and enter the hall The celebrities.
After that, you go home and back to your home. Eventually Professor Magnolia should come to your house and she will want to talk to you. She congratulates you on successfully completing the battle tower and becoming the new Pokémon champion.
She will hand you the Master Ball shortly after. Because you have to go home at the end of the game and talk to him, you can't miss him.
You can get another Master Ball by winning it with the Loto-ID. You can win a Master Ball after matching five or more numbers through the identification system. To make sure you don't miss a chance to win the Loto-ID, check your Pokémon Center computer to see if you won that day. To increase your chances of winning, go out and catch as many Pokemon as you can come across.
