Rare Pokemon Dolls (for the dream world, not the real one) will be made available in the catalog to members of the trainer club. Over the next few months, passwords will be arriving in trainer club accounts’ message inbox, unlocking certain decor dolls. The first password unlocks Reshiram, Zekrom and Keldeo.

If you don’t have a trainer account but want one, click on the above link and there should be the option to join in the top right corner. Obviously to receive the dolls you will need a dream world account.
