Ok, I have just received an email regarding these two cards, it will make some people happy and others cry. This is the situation:
The Donovan and Mitsurugi promo cards given out at the Street Fighter Nationals are not and never will be legal. These cards were not meant to be sent to us, in fact these cards were not meant to be sent to anyone.
I'm really sorry if you received the card and, like me, went mad building an all conquering Mitsurugi I'm Never Going To Die Deck, it will never see tournament play. There are two options:
A: You send the cards back to me and I will send you replacement, unreleased league foils.
B: You can keep the cards, grumble a bit, add them to your folders and only ever use them for casual play.
I know this is a right royal pain, but accidents will happen. It's up to you guys though, so if you couldlet me know your thoughts that would be cool.
