Contains 36 booster packs, each booster contains 15 cards(1 rare, 3 uncommon, 11 common). The Revised Edition of the basic set was released in April 1994 with 306 cards. The white-bordered set "cleaned up" several rules and graphical oversights from the previous Unlimited basic set. Note: Due to the printing process, it is possible to get land cards in an uncommon or common card slot. The chance is approximately 21.5% for uncommons and 38.02% for commons. This is because they put lands on all the uncommon and common sheets. Although you should never get a land in a rare slot it is known to happen due to unrefined packaging processes used when this set was produced.
