The DCI sanctions tournaments for a variety of games. As of 2009 the DCI has sanctioned more than two million Magic tournaments. Unlike those of many other game producers, a significant proportion of DCI events are organized and run by independent businesspeople and hobbyists, as opposed to by retailers.

Magic: The Gathering

The DCI maintains rules and assigns players ratings for three basic categories in Magic: Constructed, Eternal, and Limited. A fourth rating category, Composite, is the average of a player's Constructed and Limited ratings. Each category supports a number of related tournament formats. A player's tournament performance in one of the categories does not affect their rating or ranking in the others, except Composite. The DCI has recently introduced a new rating category, called Total rating. This rating will replace most of the existing individual ratings at the beginning of 2010. Although no rating category will cease to exist, Total will replace the other categories for rating-based invitations and byes.

Separate groups of rankings are maintained for team and multiplayer variants. Sanctioned team and multiplayer uses teams composed of two or three players. There are several team and multiplayer variants, each given its own ratings category. Rules are also provided for other multiplayer variants, but only the formats mentioned above are ranked.

Constructed

In Constructed tournaments, decks must consist of no fewer than 60 cards, and no more than four of any one card. The basic lands, however, may be used in any quantity. A banned list of specific cards is maintained for each format.

Additionally, a 15-card sideboard is permitted, from which a player may modify his or her deck during a match to better deal with their opponent's strategy. Following the first game of a best-two-of-three match, each player is permitted to replace any number of cards in his or her deck with an equal number of cards from his or her sideboard. The original deck configuration is restored at the conclusion of the match.

    .
  • Block Constructed permits only cards from a single "block" of sets. Most Block Constructed tournaments use the most recent block, but organizers may sanction tournaments using any block.


New sets are released approximately every three months. A set is legal for constructed play on its official Wizards of the Coast release date.

Eternal

Eternal formats follow the basic Constructed format rules for deck construction, but expands the available cards to include virtually all published Magic sets. The ratings are kept separate from other Constructed formats because of the barrier to the participation of new players. While ratings and rankings are maintained for this category, only Limited and Constructed format rankings are used for invitations to major tournaments, like Pro Tours or World Championships.
  • Vintage (formerly Type 1) allows every published Magic set with the exception of the silver-bordered Unglued and Unhinged sets. All cards from the remaining sets are allowed except cards involving ante, any card that is "flipped" on the table, and Shahrazad, which involves playing a "subgame", as the DCI considers such cards inappropriate for tournament competition. The Vintage format is the only format to have a restricted list in addition to a banned list. Each card on the restricted list is limited to one per deck. This is the only format that allows the "Power Nine
    Power Nine
    The term Power Nine refers to a set of nine specific cards in the game of Magic: The Gathering. These cards were only printed early in the game's history and consist of Black Lotus, Ancestral Recall, Time Walk, Mox Sapphire, Mox Jet, Mox Ruby, Mox Emerald, Mox Pearl, and Timetwister.The Power Nine...

    ".
  • Legacy (formerly Type 1.5) uses the same sets as Vintage, but has no restricted list and a separate banned list.


Vintage and Legacy were very closely related until September 1, 2004, when R&D decided that splitting the formats was a good idea. Certain cards formerly banned in Legacy were unbanned and the format was allowed to develop on its own. Legacy once had a reputation for being the "poor man's Vintage" but today has developed into a format very distinct from Vintage.

Limited

Limited tournaments are based on a pool of cards which the player receives at the time of the event. Any number of basic lands may also be added to the deck. The decks in limited tournaments are a minimum of 40 cards; all the unused cards function as the sideboard. There is no 4-of-a-kind limit per card as there is in Constructed decks.

There are two common types of limited tournaments.
  • Sealed deck: Players each receive six booster packs of 15 cards.
  • Booster draft: Players each receive three booster packs of 15 cards. After being seated around a table, each player simultaneously opens one booster pack, selects a single card, and then passes the rest to the next player over. After all players have drafted fifteen cards, they each open their second pack, and drafting continues. Players examine privately the cards they receive; direct communication between drafters is not allowed. A booster draft normally comprises eight players, but sometimes fewer will suffice. Once players have built their decks, they compete against the other players in the draft.


In addition, one limited format which is no longer commonly in use and has been deprecated.
  • Rochester draft: Players each receive three booster packs of 15 cards. One player's first pack is opened, the cards are placed upon a table for all to see, and the players take turns selecting one card at a time until the pack is exhausted. The next player's pack is then opened, and drafting continues. A Rochester draft normally comprises eight players, but team Rochester uses two teams of three players each, who may communicate non-verbally during the draft.

Pro Tour

Multiple Pro Tours are run every year around the world. A Pro Tour season begins in January (starting with the 2006 season), with an event held roughly every two months culminating at the World Championship

The Magic: The Gathering World Championships have been held annually since 1994. It is the most important tournament in the game of Magic: The Gathering, offering to the winner a cash prize of $45,000.

. In the months preceding each Pro Tour, local qualifiers (PTQs) are held around the world, where invitations are earned. Players accumulate Pro Points by attending Pro Tour events and can receive many more by placing highly. Pro Tours are invitation-only events, and only players with either a PTQ invitation, high number of Pro Points, or high DCI ranking can attend.

Winning a Pro Tour is most competitive Magic players' ultimate goal. Currently, each Pro Tour carries a total purse of $240,245 [US], with the winner receiving $40,000 [US] (the exact payout varies by player's final standing). Other benefits to top finishers include invitations to future Pro Tours, with the highest-ranking players over the course of several Pro Tour events receiving additional prize money for travel and participation.

World Championship

The most prestigious tournament (and Pro Tour) of all is the World Championship

, where the best of the best play against each other until the world champion is crowned. World Championships are played over five days, and include both individual and team formats. A required invitation is obtained either by placing very highly in a National Championship, or having a high enough DCI Total ranking. The World Championships are now held at the end of the year usually in November/December, most recently (2010) in Chiba, Japan.
