Unglued was the first Magic: The Gathering supplemental set to be used outside of normal Magic expansions. It was released on August 11, 1998 as a standalone, fun set.
The set included 83 silver-bordered cards, five black-bordered cards (basic lands) and six Token creatures. The lands are special full-art lands which have extended artwork inside an oval frame stretching from the top to bottom of the card. On top of that oval frame is a round gem of the appropriate color with the (at the time current) tap symbol. At the bottom is a slightly larger gem featuring the appropriate mana symbol. The top left corner has the name of the basic land while the bottom left corner simply reads "Land" with Artist and copyright information as well as collector number running along the bottom. Unlike other sets that feature up to four distinct arts per basic land, Unglued only has one art per basic land.
The rest of Unglued are silver-bordered joke cards which are still functional. Names, flavor texts, types and mechanics as well as the art featured on the card[8] parody the game, individual cards, concepts, the history or players of the game. Unglued and its followup Unhinged are also the only sets in which the artwork of non-Planeswalker cards of extend outside the artframe. The card B.F.M. (Big Furry Monster) even extends over two cards. Some cards have specialized frames allowing for other jokes. Unglued also makes special mention of Chickens and Clamfolks as creature types. Chickens were a minor theme.
