102. Authorized Cards: Alpha cards (cards from the first print run of the core set) may be used in decks containing non-Alpha cards only if all cards are placed in completely opaque sleeves and only if the sleeves could not be considered marked. If sleeves are not used, Alpha cards may be used only in decks that consist exclusively of Alpha cards.
Participants may not use cards from special sets or supplements with alternate backs, squared corners or gold borders. (Examples: Collector's Edition, Pro Tour Collector's Set, World Championship decks.) Players may not use silver-bordered Unglued(tm) or Unhinged(tm) cards. Unglued and Unhinged basic land cards are allowed in sanctioned Magic tournaments.
Players may use cards from special sets and supplements with black- or white-bordered cards published by Wizards of the Coast that do not have alternate backs and/or squared corners. (Examples: the Anthologies(tm), Beatdown(tm), and Battle Royale(tm) box sets). However, the card(s) must be otherwise legal to play in that tournament's format.
A series of official promotional cards called textless spells are allowed in DCI-sanctioned Magic tournaments. However, the card(s) must otherwise be legal to play in that tournament's format. These cards should be interpreted using their current Oracle(tm) wordings.
