i forgot to include im gonna catch it no matter what

Go to the Pokemon Diamond Cheats and Click in the one that says Secret-Dialga.I think it
would help you.

dont use the master ball!!! i would give u a whole bunch of mine
but......................... no wifi

dont use master ball

dialga is the easiest legendary to catch! just blast it with ultra balls!

use the master ball on cresselia, it is the hardest legendary to catch.

1. Use your strongest Pokemon on Cyrus
2. After Cyrus' battle, heal your party as soon as possible, you have an chance to save
your game
3. Bring in Dusk, Ultra, Timer or Pokeballs (Which works as well, no joke, I've tried like
50 times)
4. After you caught it, go back where Dialga was standing and go further, you'll see a
ADAMANT ORB. Which increases Dialga's power even stronger!

I can help you in a certain ways as you like! :D

~PS: Save your Masterball for Arceus once this event is out~

Seung always gives out the better answers...

im lucky i used my masterball and got nine from maddy.

Yeah... I made a mistake on trying to catch dialga with a master ball you shouldn even
bother catching aself uxie or mesprit theyre all very weak if you want to use your master
ball use it on giratina or heatran.

Not on Heatran and Giratina!I captured them in a Dusk Ball.But now a glitch took my
Heatran away...T_T'

The Master Ball should be used on Arceus.

AZLEF!!!!!!!!!!!!!!!!!!
:)

i caught them in dusk balls too!

this is my friends acc. Should i use the masterbll on aazelf(the river pokemon that
runs)?

It Mesprit and Cresselia that do.

I know,they are ANNOYING.

i have pearl, and i managed to catch palkia USING ONLY 3 ULTRA BALLS. it was fairly easy
though. mesprit and cresselia can be much of a neussiance, i used master ball on mesprit,
and cresselia ultra. heres a tip: when you manage to attack mesprit or cresselia, THE
DAMAGE ON THEIR HP WILL STILL BE THERE WHEN YOU FIGHT THEM AGAIN. or just a wobuffet or a
trapinch with that skill that won't allow you to escape. (arena trap and forgot the other
one)
