Having trouble catching a legendary Pokémon? Look here to catch that legendary Pokémon!

Bring about 50 Ultra and Timer Balls because this battle will take forever. Go to the location of the legendary Pokémon of your choice. Battle it until it gets into the red zone (10 HP or less) Then,start throwing Ultra Balls at it. It's easier if ya have put a status aliment on it. When you've reached around 20-30 Ultra Balls,start using Timer Balls because they will work better around this time. SAVE BEFORE STARTING THE BATTLE FOR 2 REASONS!!! 1st reason,you only have a limited amount of time before the Pokémon uses the last ditch move,Struggle,which hurts the Pokémon using it. 2nd reason,if you accidentally defeat it or it defeats you,you can reset the game so you won't have to do everything over again.
