<Li> Cards banned in a specific format may not be used in decks for that format . Cards restricted in a specific format may only have one copy in a deck, including sideboard . </Li> <P> Pauper is a Magic variant in which card legality is based on printed rarity . In Pauper, only common cards are legal, or rather any card printed at common rarity, by deck construction rules . It is largely known as a Magic Online format, although paper Pauper events have been run using the MTGO legality list . It was added as an official format on Magic Online December 1, 2008 . </P> <P> The Standard format is continually one of the most popular formats in the constructed deck tournament scene . It is the format most commonly found at Friday Night Magic tournaments, played weekly at many hobby shops . Standard's former name was "Type 2". This format generally consists of the most recent three or four "Block" releases . The release of the first set of a new Block in Autumn (usually the first Friday in October) triggers a rotation; the new Block becomes Standard legal, and the oldest two blocks rotate out . (The previous rule was using two recent "Block" releases plus any core sets released between the older set of the block and the first set that would make that block rotated out). The current Standard set includes the Ixalan block, Dominaria, Guilds of Ravnica and Core Set 2019 . Additionally, cards appeared in Welcome Deck 2017 and cards from Global Series: Jiang Yanggu & Mu Yanling (only applied to events inside People's Republic of China) are also legal in current Standard . </P> <P> For a list of which sets were legal in the past, or notable deck archetypes, see Timeline of Magic: the Gathering Standard (Type II). </P>
