How to Catch Legendaries
To catch a legendary Pokémon, you will need to first weaken it by battling it. Once it is weakened, you can then throw a Poké Ball at it. The best type of Poké Ball to use is an Ultra Ball, but you can also use other types of Poké Balls if you have them. If the legendary Pokémon is very powerful, you may need to use multiple Poké Balls to catch it.
Some legendary Pokémon can only be caught after you have completed certain events in the game. For example, Darkrai can only be obtained from the Lunar Wing and Member card events, while Shaymin can only be obtained from the Oak's Letter event.
