It has to be traded from Diamond, Pearl, or Platinum. From there, it can only be gotten in an event, by getting an item or getting the Pokemon outright.
The only way to do this is by using an Arcues obtained in the 12th Pokemon movie, take this arcues to the ruins of alph, there you will meet Cynthia who will now explain that arceus can create new Pokemon, i will spoil no further.
you have to get it from Pokemon platinum or diamond
you can't
You cannot get it in-game; you have to trade it from D/P/Pt, or get it from an Arceus event for HG/SS.
i don't no if u can migrate Pokemon to SS and HG but i no u can trade them.Im trading or transfering my pichu and arcues to HG once i get it!!
I wish you could because i really wanna catch celebi, mew, deoxys, and jarachi and arcues

You cant get an arceus in soulsilver or heartgold at all!
