Tips

You need an Arceus from an official distribution event at the front of your party.
Cynthia only lets you onto the Mystri Stage when Arceus is your only Pokémon; leave the rest in the PC in the cabin.
You choose one of Dialga, Palkia or Giratina, and it arrives at level 1.
Each comes holding its orb: Dialga the Adamant Orb, Palkia the Lustrous Orb and Giratina the Griseous Orb.
Picking Giratina is the only legitimate way to get a Griseous Orb in HeartGold and SoulSilver.
