Not to sure, but apparently there was going to be a Celebi event for Soulsilver and Heartgold (maybe only for Japan though). The only another events I could think of would be the mew one, which ended on the 31st of oct. Also, the spiky Pichu event. O and the Jirachi event! (ended awhile ago...). Maybe look at gaming sites a bit more to stay in tune with them... try Serebii.
Hope i helped a bit :I
You'll need to trade for it from Pokemon HeartGold. It is not avilable in the wild in Pokemon SoulSilver.

make your Pokemon hold pokeballs then trade them over
Trade Pokemon that you have more than one of for Pokemon that you don't have. If you have AR, you can just clone Pokemon to trade.
you cant. you have to trade it from soul silver, diamond, pearl, and platinum.
Trade or wait for an event.
You get him in trade with a friend or you do the event that past already.
You can't, you must trade from Emerald (which had an event to get to Mew), or trade from Pokemon Ranch (if you unlocked it).
deoxy is unavalible is Pokemon soul silver unless a Pokemon envent,trade, or migrateNintendo Event...
You get him in at a real world Nintendo Event. The last event recently ended, so you'll have trade with someone to get him.
If you mean soul silver, it is yet unknown you have to trade the event arceus to it to get giratina, dialga or palkia.
I have a Shiny Event Raikou, but it depends on what you're going to trade. If you want to trade then put a message on my message board. - PokemonShaymin102
I would suggest the Global Trade Station. Deoxys is an event pokemon and the event has long since passed
you got to get it from a wifi event in diamond and pearl,then trade it to soul silver. But if you don't want to get diamond, then wait for an event, you can get him in Pokemon ranger- something with an "A"
Celebi cannot be found in the wild in Pokemon SoulSilver. Celebi is an event Pokemon, and can only be obtained through the event. You will have to trade for it or cheat for it to get it.
Darkrai is actually obtained through event's so try to stay up-to-date with that otherwise your going to have to trade with someone who actually has it.
I'm not sure there is a way to trade Pokemon from and GB game to a DS game. They obviously don't work with the dual slot feature. I'm going to say 'no' but there might be indirect ways to do it.
