It is currently uncertain when slifer will be legalized. However, Obelisk The Tormentor and The Winged Dragon of Ra have legalized versions, so the chances of Slifer being legalized as well are good.
There is currently no game-legal version of Slifer the Sky Dragon.
The legal version of Slifer was released in December 2011 in Japan, and the end of June 2012 for US/CAN.
There is currently no game-legal print of Slifer the Sky Dragon. Obelisk has a TCG and OCG print, Ra has an OCG print, so there will eventually be a legal Slifer.
no, but they are making one
so far, there is no combination of the god cards made. but, it could be a possibility in the future, once they release tournament legal slifer.
Slifer's ATK and DEF is X000 where X is the number of cards in its controller's hand. So if you have five cards in hand, Slifer is 5000/5000. The non game-legal print has no effect text so doesn't explain this, but the game-legal version does.
The legal Slifer has already came out in the Shonen Jump magazine they will most likely reprint it soon like they did with the other cards.
legal 'Obelisk The Tormentor' came out in the Jan 2010 issue of Shonen Jump, and legal 'The Winged Dragon Of Ra' came out in the Jan 2011 issue of Shonen Jump so im only assuming that the legal 'Slifer The Sky Dragon' will come out in the Jan 2012 issue of the same magazine.
No, the legal versions of Obelisk and Ra do not have serial numbers on the bottom left. There is no legal Slifer yet.
Obelisk currently has a legal print, Ra's is coming out soon in English, Slifer has yet to have his legal version announced, but it's pretty certain he will have one.
There is no game-legal print of Slifer just yet. Ra has had his game legal version released in Japan, but not in English yet. Slifer hasn't even been announced in Japan at the moment, but should be eventually.
No. God Cards are not legal game cards, so cannot be used in tournaments.There are a few legal god cards like ra and obelisk but not slifer not yet
