It doesn't have one.
it depends on how many cards u have in ur hand
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.
Slifer the Sky Dragon does not have an official passcode.
There is currently no game-legal version of Slifer the Sky Dragon.
The theme song for when Yugi summons Slifer the Sky Dragon in the Pyramid of Light is called Slifer The Sky Dragon Theme.
Slifer the Sky Dragons ATK and DEF are calculated for every card in your hand,1000 points for card.I suggest using the following Spells:infinity cards x1 pot of greed x10.
Slifer the Sky Dragon is a God and has no code. If you are playing on the PSP get the Yu-Gi-Oh tag force 1 and it will allow you 3 copies of the Slifer card.
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.
Slifer the Sky Dragon does not have an official passcode; therefore, it cannot be obtained in Stardust Accelerator by password.
Yugi received Slifer the Sky Dragon from Strings per the guidelines of the tournament that each Duelist must ante their most valuable card.
His attack is X000. He gets 1000 POINTS from the number of cards you have in your hand. :)
Slifer The Sky Dragon goes up to $75
