As of writing this, there is no way to legally get Arceus in the U.S.A. Between the dates of November 7 to November 15, 2009 Toys "R" Us gave him away, but since then the events that have given him or the Azure Flute (used to make the stairway to the Hall of Origin appear) out have only been available in Japan, and the Arceus will only be given to Japanese region game cards.
You can't catch Arceus without cheats.. You can get it when an event is going on about Arceus..
You can only get arceus without cheats if you go to an event.
Without cheats, you can only obtain Arceus through a Pokemon Event.
You can't.

You can't get him without events or cheats. For Darkrai, Manaphy and Arceus you need a event to capture him.

Arceus cannot be caught legitimately in ANY pokemon game.
