well, I used a lot of ultra and timer balls.
i would prefer giratina or if you have the regis from ruby,sapphire or emerald i prefer regigigas
a master ball!!!
In order to open the Regis caves in Pokemon Emerald you first have to go to route 134 and dive into the cave. When you are in there use dig. The first Regi cave is located in the desert.
you can use master ball in caught the groudon
depends how you use it, and what for. If, for instance, it was a dive ball and you used it on a fire pokemon, it would be crap.
You can't (unless you use cheats).
birth island you meet deoxys on level 30 use master ball or a ultra ball
Pokemon ruby/ sapphire/ emerald= latios/latias. Pokemon diamond/pearl/platinum=cressila.
use ultra ball until you catch it but if that doesn't work continue with the timer ball and that is sure to do the trick
you cant. use emerald or sapphire ,ruby for all the regis and there after go to snowpoint city to get regigas.
you don't get the master ball from may in emerald, you get it in the team aqua/magma hideout in lilycove. that is the only way to get a master ball , unless you win the loto ticket drawing or use an actionreplay or gameshark.
Depends what pokemon. If something like Raqyazua, just go ahead and use a master ball if your lazy. OR. Have a pokemon with sing and stun spore. Use a like a lv 40 pokemon with super effective attacks agiasnt it. Use a great ball/ultra ball when the pokemon is down on red, asleep, and stunned
