The theatrical promo card for the anniversary movie has apparently been revealed.
It’s the alternate art of Obelisk the Tormentor, based on its appearance in the Yu-Gi-Oh! The Dark Side of Dimensions movie!
Apparently for the German release, only 4000 copies will be issued (and so far it’s only confirmed for Germany at the moment)
