Saviors of Kamigawa (SOK) is the ninth expansion in the Magic: The Gathering trading card game, released on August 15, 2005. It is the third set in the Kamigawa block and is set on the plane of Kamigawa, a world inspired by Japanese mythology.

The key mechanics in Saviors of Kamigawa are:

• Spirits: Spirits are a major part of the Kamigawa world, and they play a significant role in SOK. Many cards in the set depict spirits, and there are several cards that interact with them.
• The Afterlife: The afterlife is another important theme in SOK. Many cards in the set deal with death and the afterlife, and there are several cards that can bring creatures back from the dead.
