Catch all 3 legendary pokemon in pokemon platinum

how can we catch all 3 legendary pokemon in pokemon platinum ? i really want to catch this legendary pokemon , i know we can catch them using masterballs but i don't have 3 masterballs what to do in this problem ? thank you for your help !

You can have more then one master Pokemon ball in pokemon platinum See this thread : http://forums.techarena.in/video-games/1195692.htm

If you don't have master ball you can use 25 net balls on Mesprit, and 25 duskballs on Azelf and Uxie.

Use any pokemon that have hypnose or use a golbat with amazing speed and his main move is the MEAN LOOK and any use birds on it .

You can Obtainable legendary pokemon in Platinum ball like :
Heatran
Cresselia
Regigigas
Mesprit
Azelf
Regirock (Must have TRU Regigigas)
Uxie
Regice (Must have TRU Regigigas)
Registeel (Must have TRU Regigigas)
Dialga
Articuno
Zapdos
Moltres
Palkia
Giratina

And the other legendaries must be traded for over GTS or via migration from Ruby, Sapphire, FireRed, LeafGreen or Emerald.

The easiest way is as said by reddevil6 catch a Golbat and train level 60 and while encounter the legendary bird use it mean look and weaken it . if you cant do this save your masterball after the league and use it on any legendary birds . you can get next two masterballs from the solaceon town news area but it will take time i think 2 days . Hope this helps you .

You can use some tips from me to catch the ledgenaries
1. Go catch a pokemon that knows any move that can make pokemon asleep
2.Buy Ultra Balls, Timer Balls, Dusk Balls, Quick Balls and other balls
3. Save before you chellenge it
4. Go and fight them
5. Start off by trying your luck with a quick ball
6. Make it sleep using the pokemon you brought
7. Cut its hp to the red zone without defeating it(if it wake up just make it sleep again)
8. You can use a Ultra Ball and see if it works
9. If not, switch to another pokemon and keep on switching(if it wake up just make it sleep again).
10. After 20 turns, use a Timer Ball
11. If it does not work, use a dusk ball if its night
12. If you lose all your pokemon, ran out of balls, or if you defeat it restart your DS and try again.:ohyeah:
