Either you have to go to the distortion world entrance in Spear Pillar or go to turn back cave after beating the elite four and press "a" on the spinning vortex in giratina's room.
you cant
you cant only platinum unless an action replay code
you get giritina in the distortion world. It really is quite simple
Absolutely- Palkia, Uxie, Azelf, Mespirit, Creselia. Rarely- Manaphy Never(cant catch)- Dialga, Giritina
legendarys that dont have a gender cant lay egg so 0 steps
Platinium is used as a catalyst and in electrical components, jewelry, dentistry, and electroplating.
you cant find a master ball but Cyrus gives you one to catch giritina after u beat him for the 2nd time
you could get a giritina from a trade or action replay
If both of your Pokemon are legendary Pokemon you shouldn't take one of them out or else you cant put them back in. For instance if you are Giritina you cant put in another legendary in your team but you can put regular Pokemon in.
yes platinium is much more expensive than gold
By either capturing a miscrit(1platinium), buying a miscrit(1 platinium),Daily spin(2/20 platinium) or wishing well(1 platinium).
you can only get darkria in Pokemon platinium if you get the wonder card that was a Pokemon event last year.
