Standard is the most widely supported format among all sanctioned tournaments, though not necessarily the most popularly played for casual games.
It typically allows only cards from the latest two blocks and the most recently printed Core Set, though this has been somewhat altered recently. Once a new block is introduced, the oldest block from Standard rotates out and becomes illegal to use.
Constructed decks must contain a minimum of sixty cards. There is no maximum deck size; however, you must be able to shuffle your deck with no assistance. If a player wishes to use a sideboard, it must contain up to fifteen cards.
With the exception of basic land cards, a player’s combined deck and sideboard may not contain more than four of any individual card, counted by its English card title equivalent. All cards named Plains, Island, Swamp, Mountain, and Forest are basic.
The following card sets are accepted in Standard tournaments:
