Kamigawa

Kamigawa was the 10th block released for Magic the Gathering. It takes place in the titular plane. It introduced the the Ninjutsu mechanic, which is awesome. The block came after Mirrodin block, which was one of the largest and stinkiest blocks of cheese Magic had ever seen. Subsequentially, CoK-block was well below the general power curve compared with other sets.

The Plane Proper

Kamiagawa is Magic's Oriental Adventures setting; a fantasy realm based upon Japanese mythology, most prominently in the form of being divided into two realms, one inhabited by mortals and the other inhabited by Kami -primal spirits who embody the various elements, objects and other aspects of the material realm. The Kakuriyo or Reikai is the spirit world where the kami dwell; its other half is that of the Utsushiyo where mortals live. Utsushiyo is divided into five lands which correspond to the five Colors of Magic.

Native races of Kamigawa consist of: Humans, Soratami, Orochi, Kitsunes, Nezumi, O-bakemono and Akki.
