About Unlimited Edition

The collectible card game Magic: The Gathering published nine base sets from 1993–2007, also referred to as core sets. The base sets were considered descendants of the original Limited Edition, and shaped the default setting and feel of Magic. These sets consisted entirely of reprinted cards. These cards were generally simpler than cards in expansion sets, omitting multicolored cards, and used only the original abilities and keywords of Magic such as Flying and Trample. This simplicity led to many cards from these sets being considered "staples" of deck design. All cards were given a white border to mark them as reprints, with a few exceptions. From Fourth Edition in 1995 onward, a new base set would come out once per two years in the spring or early summer; for tournament play, that set would be legal for two years in the Standard format until the next core set replaced it.
