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 allow cards from:
- All Magic card sets
- Any edition of the core set
- All special sets, supplements, and promotional printings
Cards from expansions and special sets (e.g., From the Vault, Magic: The Gathering—Commander, Duel Decks and Conspiracy) are legal in Legacy format, as of their date of release.
All promotional cards are legal in Legacy, too, on their date of the release.
The following cards are banned in legacy tournaments:
