World Championship Decks were specially packaged versions of four of the top ranked decks used during the Magic World Championships, released by Wizards of the Coast for the years 1997 through 2004. The cards produced were gold-bordered versions, and thus are not legal for use in DCI-sanctioned tournaments. The cards were also stamped with the player's autograph. Each competitor's release included their 60-card deck and 15-card sideboard, 12 blank proxy cards, and cards with a printed decklist, a biography of the player, and an overview of the four decks release for their respective year. Due to the larger than usual collection of 90 cards per product the deck boxes for World Championship Decks were slightly larger in size than typical Theme deck boxes of the era.
