Use a dusk ball instead during the nighttime.
Master ball
get him down to low healt then use an ultra ball
you cant, you will need a master ball. I wasted mine catching Dialga yes u can use a heal ball i did it b4 im proved by pkmn master
Before you find Dialga in Diamond or Palkia in Pearl or giratina in platinum, Cyrus will give you a master ball. I'm assuming this is so you can catch Palkia, Dialga, or Giratina.
Using dusk balls at night tend to work the best. But if you get it to sleep, an ultra ball can work too.
Defeat team galactic then use it to catch giratina :)
The best ball to catch Giratina is the Master Ball but the next best and effective options would be the Dusk Ball or the Ultra Ball.
no
if you dont have a master ball, use dusk balls at very low HP
Either, master ball, (if you haven't used yours givin to you by professer rowan) ultra ball, or timer ball.
I'm not quite sure what your talking about, but I would have to say that you would not have to catch it in a Master Ball.
You should have used a dusk ball. LOL of course its bad......Master ball should be saved for a powerful roamer like Zapdos, Moltres and Articuno (yes, you can catch them in platinum without migrating via Pal Park and with no cheats).
