In Pokémon SoulSilver the only way to get Arceus is to trade the Arceus from the event that happened in 2009 over into SoulSilver or HeartGold, the event is no longer active so if you didn't get one then you would have to wait for the next Arceus event or you could use a cheating device in order to cheat for it.
You can't find it wild and cath it. The only way to have one is by trading on th event Arceus from last year.
Other than that, buy and Action Replay.
You cannot find Arceus in Pokémon SoulSilver, the only possible ways in order to get Arceus in "SoulSilver" is via a Nintendo event, via a cheating device or by trading with someone who has gotten one.
You can only get Arceus from Pokemon D/P/Pt.
Usually Arceus can only be obtained through Pokemon events, and all the soulsilver events passed :(
Through cheats
you have to have arceus, then go to the ruins of alph and a guy will show up
You'll need to trade from the Pokemon HeartGold, Diamond, Pearl, and Platinum.
i am sorry but you cannot obtain arceus in Pokemon heartgold or soulsilver.
Yes you can get Arceus if you have a Pokemon platinum,diamond,or pearl and you have giratina dialga and palkia trade them to your Soulsilver and then a mountain will appear somewhere and then Arceus will be in there
Only with hacks
You cannot catch Arceus in Pokemon Soulsilver nor Heartgold, You must either transfer a Arceus from D/P/Ptt or Receive one through the Arceus Event.
Nope arceus is one of those unobtainable Pokemon along with Shaymin, Darkari,Manaphy
You can't get arceus in Pokemon soulsilver unless you trade from another Pokemon game.
