well after you beat the eltie 4 and catch dialga palkia and giratina.you have to start going to jufibille city alot because this dude in a purple shirt gives you poketch aps and after you disturb the three you can chase them all over sinnoh
here is some extra advice:after you complete the sinnoh pokedex and you ask rowan for the national pokedex he will give it to you.then in eterna city the house accross the street from the gym to the left oak is in it so talk to him and he tells you that moltres articuno and zapdos are in sinnoh. and you also chase crescellia you have to catch a boat in canalave city to................... i forgot what island it is but it is not iron island.and when you awaken crescellia she leaves a feather behind.grab the feather and go back to canalave city and there is a house next to the dock. go in and give the feather to the kid in bed .so in the end' you cannot only catch uxie azelf and mespirit but also zapdos articunos and moltres plus crescellia.
Uxie, Mespirit, and Azelf are unavailable in Pokemon SoulSilver. They can, however, be traded from a Diamond, Pearl, or Platinum game, or transferred from a Gen III game.
