Asian-English cards are cards printed in English for distribution in Asia outside of Japan and Korea. They are distinguished from English cards printed for English regions mainly by the Yu-Gi-Oh! logo on the cards' backings and set packaging, and the region identifier "AE" in their set number, though prior to Invasion of Chaos Asian-English cards did not use the region identifier and had the same set numbers as their North American English versions. These cards are only legal in Asia outside of Japan and Korea; they are not legal anywhere else.
