If you're heading to YCS Milan you may want to read this as it concerns the legality of SHONEN JUMP promotional cards, which was put into question last week by impending policy changes.

Many of you will already have heard that there is a new policy document to be published soon, with a significant change to the card legality rule for European events. No matter which fragmented information you have received so far, I confirm that this new policy DOES NOT APPLY for the YCS. Duelists will still be able to play their SHONEN JUMP promo cards, if they have any. This will be announced on our website this week.
