Time Spiral was codenamed "Snap" during development. This design was achieved through keywords and mechanics that interact with time, as well as cards based on those in previous sets, to promote a sense of nostalgia. In his preview articles, Mark Rosewater described Time Spiral as an expansion focused on the past, with its successors, Planar Chaos and Future Sight, to be centered around the present and future respectively. The cards were sold in randomized packs, both as the typical 15-card booster packs and in larger 75-card tournament packs. Four different theme decks, 60 card decks with themed, fixed composition were released, each featuring a different aspect of the set. Time Spiral is typical among the first sets of a Magic: the Gathering block in that the cards are sold in four different forms.

Future Sight focused on the future, both in that it includes cards from settings not yet explored in previous sets as well as including game mechanics that did not exist until later sets. The references are reflected in the card design, which incorporates special rules from older sets, and in special "Timeshifted" cards, which are cards reprinted from older sets using the older card design (abandoned three years previous with the 2003 release of Core Set 8th Edition.) Planar Chaos focused on the present, referencing previous Magic: The Gathering cards, but changing them in some way, such as changing their color or shifting their permanent type. Time Spiral focused on the past, and is laden with references to previous Magic: the Gathering sets. It is set on the plane of Dominaria, the first time that that plane had been visited since 8th Edition. Time Spiral is a Magic: The Gathering expert-level block consisting of the expansion sets Time Spiral (October 6, 2006), Planar Chaos (February 2, 2007), and Future Sight (May 4, 2007).
