Classic Tournament Format
This format is also known as the "Type I" tournament format.
This page contains updates through the 03/01/01 tournament announcement.

Legal Card Sets:
Decks can be composed of cards from any edition or expansion of Magic which use the normal card back (unless the judge says otherwise).
Collector's Edition cards are not allowed. Promotional cards are allowed. The poker cards are not allowed. Unglued cards with a silver border are also disallowed. Portal cards are not allowed unless they have the same name as a legal card. In this case, they play as the legal card text and not the Portal card text. Starter cards follow the same rules as Portal cards.

New card sets become effective on the first day of the month following their introduction. If a set is released after the 15th day of a month, then the set's effective date is pushed out to the first of the second month. For example, a set released on January 8th is legal on February 1st, and one released on January 25th is legal on March 1st.
