Time Spiral is the fortieth Magic expansion and was released in October 2006 as the first set in the Time Spiral block. Time Spiral is the first expansion to include a separate bonus subset of cards.
Time Spiral contains 301 all new black-bordered cards (121 commons, 80 uncommons, 80 rares, 20 basic lands) and a bonus reprint subset of 121 "timeshifted" cards. Time Spiral was nostalgia-themed. Most of the cards in this expansion reference previous cards in some way. The expansion symbol of the set is an hourglass to reinforce the time themes and to imply the idea that time is running out.
