Ok I know how to to get Shaymin, (In case if you don’t know how to get Shaymin you talk to Damian in the dream world) but Damian isn’t there and I don’t know what to do does this mean I can’t get Shaymin? Please help…

Did you complete both of the Damian quests, as well as do the rematches?

If you mean the Darkrai Quest and the Kyogre Quest then yes

Im going to guess you did the rematches as well?

Do you mean the Elite 4 then no

You have to do those to get Shaymin, this includes a few others as well.

ok Thanks!!

No problem.
