Your best bet would be to trade. Ho-Oh = Pokemon Colliseum(sp?) Lugia = Pokemon XD: Gale of Darkness Deoxys = Nintendo Event i think.
It is an accessory in game boy. You will need it to play the game in two island. It can also help you to catch ho-oh, lugia and deoxys.
you can go to navel rock to catch lugia and ho-ho
You can't catch Lugia in Pokémon Pearl. You have to trade it from Pokémon SoulSilver or HeartGold. You can also migrate it from Pokémon Emerald, FireRed, LeafGreen or Pokémon XD
you have to get more then 45 gym to catch legendary Pokemon! deoxys is a legendary Pokemon
you cannot catch lugia in ruby/sapphire/... you have to trade from fireRed, and leaf green. to get lugia you have to go to navel rock either in emerald, fire red, and leaf green
You can't.

From what I understand, Yes!! I think it's a glitch, but you CAN'T catch deoxys normally in Pokemon FireRed. and in Pokemon ranbow (only in japan,and internet. even on mars
go to an Nintendo event
You can only catch lugia if you migrated it from firered or leafgreen. If you want lugia get one from heartgold or soulsilver version.
mystery gift
you must catch it and purify it in Pokemon xd gale of darkness.
Palkia, Lugia, Dialga, Deoxys, Mewtwo, and Mew
There are sadly no special events to catch Deoxys in Sapphire. You HAVE to trade a Deoxys caught in an event from FireRed, LeafGreen, or Emerald.
deoxys-beat the elite four and go to spear pillar but you have to have a kirlia in your party.make sure you have alot of ultra balls because i caught mine in a ultra ball. mew-migrate it from Pokemon emerald,ruby,sapphire,firered or leafgreen. lugia-do the same thing you did for mew .
you have to catch him on Pokemon gold or silver,crystal ,or gold and then you trade him from one of those games to firered
You can't
