no
hall of oragin
Arceas has to be caught in Pokemon diamond, pearl, or platinum, then traded to Soul-Silver and HeartGold.
Sorry no way to. Trade with diamond or pearl
Sadly, you can't get Arceus in HeartGold or SoulSilver. The only way to have it in HG/SS is to trade it from either Diamond, Pearl or Platinum.
