The seal of orichalcos?

[Ritoru Katawa]

Is that card in here. I believe its an actual card in the TCG, so I was just wondering?

[Yukiko Konohana]

It's not a real card, at least not a legal one.

The Seal is not a real card in the TCG or the OCG, and I don't see the staff approving a card that has the Seal of Orichalcos for anything except for perhaps a plot. Terribly sorry. ^_^

Rumor says it's a real card, but that's just rumor. Or fact. I'm not entirely sure on the details. But yes, it's an illegal card and cannot be used at this site. Not to mention the fact that it's terribly broken. But that's another thing. Anyways, yeah. No-can-do with it here.

"This card does exist. There are only 15 copies in existence, all in the possession of members of Upper Deck Entertainment's R&D division, who used them in the Decks they played in the Orichalcos "Duel the Master" side event at previous National Tournaments. "

There are other cards like this that are kept from the everyday person, "Power Balance" is rumored to be one, as is a copy of "The Winged Dragon of Ra" with the Hieratic text in place of the flavour text, as well as an Alternate Artwork.
