I used yami yugi and run a blue eyes/white paladin deck, don't think it made much a difference. I do have a couple prismatic cards which may have helped, prismatic/glossy cards help with rewards. Other than that I think I was just super lucky. Even if its a 1/100 chance it has to happen to someone right?
The only day to get this card is by duelin Mai? Witch one is better drop 30 or 40?
