it depends on luck because me and my friend only had 1 ultra ball and we caught it by luck and a easier way to capture Pokemon is by holding the the back buttons (L and R) while throwing a ball good luck =]
Go back to the sky pilar with your mach bike and get to rayquaza and use Timer, Ultra, and Master balls.
yes but you need 50 ultra balls
Use your strongest Pokemon, do not attack, buy 15 Ultra Balls, 5 Great Balls, 20 Poke Balls, and 6 Timer Balls. Keep using the balls, save 5 of the Ultra Balls then use a few Timer Balls. They are guaranteed to catch Deoxys.
well, I used a lot of ultra and timer balls.
TO catch my Azelf, I just kept on throwing 5 ultra balls, then 5 timer balls, then 5 ultra, then 5 timer etc. etc. (this is what I do with all my legendary Pokemon actually)
After defeating him in the galactic HQ after the seventh gym, Cyrus will give you a master ball. Do not use your master ball on dialga! Instead, use it on Cresselia or another harder Pokemon to catch.
Well, get a lot of ultra and timer balls. Bring a Pokemon who can paralyze or put him to sleep
WELL.. the best balls are ultra balls.. you have to take alot of ultraballs.. well it work for me i even caught it when it had all the health..
first get six pokemons then have about 4 or 5 timer balls and 4 ultra balls no master ball then take a lot of time and turns when palkia has red life so use our ultra balls then when u have 1 Pokemon left use some timer balls if your Pokemon is strong if not when ur second Pokemon use those timer balls i got palkia without the master ball.... hope it works it works for me
learn the braille alphabet and do what the writing on the wall in regices cave says. take many great balls, ultra balls, and timer balls

Grand Master Greevill has shadow zapdos to catch it weaken it to red hp then paralyze it use many ultra balls when your running out try timer balls i caught it with a timer ball.
