Time Spiral was released on October 6, 2006. It contained 301 new cards and a subset of 121 separately numbered reprints called timeshifted. Timeshifted cards appeared once in each booster pack and had a purple expansion symbol.

The card layout is based on modified Mirage frames. To allow the letters g, p, and y to be written without cutting the bevel of the art box, the entire frame was stretched vertically. This layout was later used for several Judge Rewards promos as well. Foil cards differ in that art and mana symbols and the frame type are shiny.
