Hard work and research... if she gave us her resources, then we wouldn't appreciate her as much.
Haha... very true. In the past three years I have become exceedingly efficient in digging up information. Sometimes I get downright obsessive over it, because like I've said... if there's two things I am it's a detective and a teacher. I love solving puzzles, and uncovering information is downright euphoric to me. Plus... a magician never reveals their secrets.... However... there are some clues and proof scattered around if you were to look for yourself....
Dual Elfin is a card in the I or N set of cards, and if you search Bakubronze on ebay you can find a couple of them as well as a tin that has the series name right on it
He found some. She was from the I set I believe, as well as the other 7. I also believe we have seen the marble form. I do know someone who has the tin with Ingram on it though. It's nice, too bad I don't like the Bakugan in it, why does Ventus always get lame exclusives?
