If you have Arceus from a Gamestop Event, brint it to the Ruins Of Alph when It's first in your party. You'll start a little quest thing, meet Cynthia, then choose between Dialga, Palkia, or Giratina, all at level 1 with their special hold-item. I chose Giratina, because I like Origin Forme.
Thanks. Any suggestions?
Oh, and I gtg, see you tomorrow?
