Sceptilite, Blazikenite, Swampertite, Cameruptite & Banettite are now available for all players via the serial code MATSUBUSA.
Additionally, I missed the release of Pidgeotite, Steelixite, Heracronite & Houndoominite awhile back, which can be received with the serial code AZUL.
edit: there seems to be a problem with the first one only working in moon and in certain regions, should be resolved soon
