You could use any ball but I suggest weakening them to 1 HP first, then putting them to sleep, then catching them with an Ultra Ball. DON'T WASTE YOUR MASTER BALL ON THEM!
The Ultra Ball is the ball with the highest catch rate after the Master Ball.
Of course, a Master Ball catches any Pokemon without fail, Legendary or not.
Yes, the Ultra Ball has a 4x catch rate than a Premier Ball, which has the same catch rate as a normal Poke Ball. It is commonly used to catch rare or Legendary Pokemon.
You can catch Arceus with an Ultra Ball. There is no limit to what Pokemon you can catch with what Pokeball you can use. However Legendary Pokemon such as Arceus have very low catch-rates and will take a lot of time to catch and can take over a dozen Pokeballs. Using the move False Swipe and putting the Legendary Pokemon to Sleep is a common method of raising the catch-rate as much as possible to improve chances of a Pokeball catching them.
You can catch any legendary Pokemon with an ultra ball as long as you get their hp down and you have to have a lot of them. Try to put it to sleep or paralyze it to make the catch easier.
You catch them with a ultra ball
a utra ball or a master ball
It would be Ultra ball,Dusk ball (if night), Quick ball, Nest ball (when really weak) & Great ball.

The Ultra Ball is the ball with the highest catch rate after the Master Ball.
In order to catch your legendary Pokemon in Pokemon Sapphire, save your master ball For Rayquaza...you can catch KYogre/Groudon/both with either an Ultra Ball or Timer Ball.
Well, you can practically catch any pokemon with a great ball, just that it has a very small percentage of getting it on the first time. Even if you are trying to catch a legendary pokemon, it is just the matter of time before you catch that pokemon/legendary pokemon you want!
it can capture a legendary Raymond Pokemon
Use A Master Ball Or Ultra Ball To Catch. But I Think It is Hard To Find Master Ball...:/
grow a pair... and get good pokemon to get the legendary pokemon's health low... then use an ultra ball over and over again until you catch it
You have to get the end of the game and find the end place where the legendary Pokemon is waiting and you catch it with the master ball you were given earlier in the game
Use the master ball you get from profe elm
