Vanguard is a supplement for Magic that debuted in Arena's Summer Season of 1997. The oversized (3" x 5") Vanguard cards aren't played like regular cards. Instead, each player chooses one of the character cards before the match begins and plays under the conditions set by that card. 
Vanguard is also the card type associated with the format.
The result of a cooperative effort between Wizards of the Coast's R&D and Events departments, Vanguard was designed specifically for casual play. The cards were released in four 8-card sets, the first two were designed together. Series 1 could also be obtained in the Vanguard Gift Box. The intent was to use the Arena League as a test market for the concept of supplemental products.  As it turned out, Vanguard was a huge success. Nearly 5,000 joined Arena during the first season, the biggest increase in league history, yet. From there, the decision to release the second group of eight cards in early 1998 (Winter Season) was simple. The third set appeared in late 1998 (Autumn Season), and the fourth in the Spring Season of 1999. 
The oversized Vanguard cards all had the same layout: adjustments to the starting and maximum hand size in the lower left, adjustments to the starting life total in the lower right, and any other effects of having the card in play described in the text box. Cards from the first three sets picture a character from the Weatherlight Saga. While the two first sets featured the central characters, the latter set depicted charachters from the periphery of the tale. The fourth set depicted characters from Urza's Saga
