I don't think Deoxes is in Soul Silver.
go to game stop say can i have deoxes theyll give you one
no
Deoxes would win because they showed on pokemon deoxys beated raquaza
i dont now
only by migration.
in the moon
you just use ultra balls on deoxes and the master on rayquaza i diod it and i got both with ultra but you need about 20 each usa quick on deoxes in the 1ST turn.
you get deoxes
you cant
you dont get a deoxes.
Depends on which game
