Legacy is a constructed format and therefore adheres to the following constructed rules:
- Minimum of sixty cards
- No maximum deck size
- Up to fifteen cards in your sideboard, if used
With the exception of basic lands (Plains, Island, Swamp, Mountain, and Forest), your combined deck and sideboard may not contain 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.
Legacy decks may consist of cards from all Magic card sets, plus the following cards: Sewers of Estark, Windseeker Centaur, and Nalathni Dragon (Mana Crypt would also be included were it not currently banned—see below).
Cards from expansions and special sets (like From the Vault, Magic: The Gathering—Commander, Duel Decks, Conspiracy, etc.) are legal in the Legacy format on the date of release of the expansion or special set.
