What Pokeball Is The Best To Catch Uxie?

Dusk and timer balls and p.sdont use the master ball its mostly used for:giritina darkrai heatran iphone!sorry if spelled wrong!and there is more legendarys that you can catch them with a master ball!the only thing is don't waste it!but you can get more master ball with first cyrus second win the lottery when its 3ids matching get it from the guy from salceon town look in all houses for him and he'll ask you for a pokemon but before you talk to him save it and if he says a pokemon you don't have turn it off and ask him again.if he dosent give you the master ball try againp.s save it again before you get the ball because if he gives you the wrong thing turn it off then he'll give you a different ball keep on trying and get to him before 1.00am you can set it on the real ds watch the time on your ds not on pokemon.hope I helped.

For UXIE you should use dusk and timer balls after you have got its HP in the red.
For AZELF you should use the same things.
And for MESPRIT well it flees from you so when you see it the wild attack it and still attack it until its in the red then after that just fire away with quick and ultra balls.

Hope I helped.

I caught a uxie with a pokeball on full hp not kidding
