cards to bear a purple and gold back that would allow players to exclude Arabian Nights from their games. In his article, "The Making of Arabian Nights", Garfield cites this as his inspiration to "be more adventurous in creating mechanics and themes". Player response against the proposed new back caused Wizards of the Coast to stay with the original backs, allowing cards from various sets to be mixed freely in gameplay. To replace the new card back, a symbolic scimitar was added between the card artwork and card text, making the first expansion symbol; every expansion set since has displayed a unique one. Cards Arabian Nights booster packs contain eight cards, two from the uncommon sheet and six from the common sheet. The set as a whole consists of 78 cards. Nineteen of these cards are U3, meaning they appear three times on the uncommon sheet, and 32 cards are U2 and are thus usually dubbed the rares of the set, although they are only 33% less common than U3 cards. Of the commons 9 are C5 and 16 are C4. Additionally the Arabian Nights Mountain is C1 and Desert is C11. When counting the commons with smaller, darker mana symbols as separate cards Arabian Nights is a set of 92 cards. The smaller darker numbers in the casting cost are referred to as series (a) and the lighter and larger numbers are referred to as series (b). Of the 78 cards, 49 have been reprinted. With 63% reprinted, Arabian Nights is second in fraction of cards reprinted in an expansion set only to Antiquities. Twenty-two of the 29 cards that have not been reprinted are on the Reserved List, meaning that Wizards of the Coast has decided never to reprint these, for concern of alienating collectors. On the other hand the Mountain, accidentally not removed from Arabian Nights, is the only card of the set that had been printed before. It is thus the first reprint in Magic outside a base set. Arabian Nights includes a few minor collation and typographical errors. One of them was the so-called "Arabian Mountain". When the decision was made to have the expansion sets fully playable with the basic set, Wizards of the Coast decided that there was no need to include basic lands in the print run, so they were removed. However, one Mountain basic land card accidentally remained on the print
