BLOCK FORMAT

Block play requires a Constructed deck, which must contain a minimum of sixty cards. All cards in your deck must be from a single block of Magic releases. So if you’re playing a Theros block format game, all of your cards must come from Theros block. There is no maximum deck size. However, you must be able to shuffle your deck with no assistance. If you want to use a sideboard, too, it must have fifteen or fewer cards.

With the exception of basic land cards (Plains, Island, Swamp, Mountain, and Forest), a player’s combined deck and sideboard may contain no more than four of any individual card, counted by its English card title equivalent.

Note: The five snow-covered lands from the Ice Age block—Snow-Covered Plains, Snow-Covered Island, Snow-Covered Swamp, Snow-Covered Mountain, and Snow-Covered Forest—are also basic lands. Snow-covered lands are only permitted in formats that allow expansions from the Ice Age block.
