Portal Three Kingdoms is the third Magic: The Gathering expansion of the Portal block, and the third starter level set. Like the other expansions in the Portal block, Portal: Three Kingdoms is designed for beginners to Magic. The setting is heavily based on the Romance of the Three Kingdoms. Each card, including each basic land, was illustrated by Xu Xiaoming, a Chinese artist.
Portal Three Kingdoms was released in Asian Markets. The cards are printed in Japanese, Simplified Chinese, and Traditional Chinese. A very short English printing run was also done. Portal Three Kingdoms, however, is not sold in America.
