Points of Interest
The Legendary supertype replaced the "Legend" creature type when the Legend rule was updated in 2004 with the introduction of the Kamigawa block. This left many legendary creatures without any creature type.
Originally, the Restricted list included every legendary creature for flavor reasons.
