Do Yu Gi Oh god cards say konami on the back?

No, the God Cards in Yu-Gi-Oh! do not have the Konami logo on their backs. They have a unique design specific to them.

Here's what you'll see on the back of the God Cards:

* Slifer the Sky Dragon: A large, winged, and serpent-like creature with a sun-like symbol in the center.

* Obelisk the Tormentor: A large, Egyptian-style obelisk with a symbol on top.

* The Winged Dragon of Ra: A large, winged, and serpent-like creature with a sun-like symbol in the center.

The Konami logo is found on the backs of all other Yu-Gi-Oh! cards.
