Its Slifer the Sky Dragon, not snyper. And the only of the god cards that has a usable version so far is obelisk the tormentor and the winged dragon of ra, and the usable version of ra in a japanese only card. Slifer has yet to come out as a usable card. The origonal set of god cards has colored backs and said on the card that they cannot be used in a duel. Recently obelisk and ra had new versions made that are able to be used in dule, however the only on in english print is obelisk.
Obelisk was available for a limited time as a free give away in the magazine called Shonen Jump. I was lucky enough to get one. I hope they release the usable version of slifer in english print. And I wish they would make an english version of ra!
