The collectible card game Magic: The Gathering has released compilation sets, reprint sets, and box sets over its history. These are distinct from core sets and expansion sets, the most heavily marketed sources of new cards. With the exception of Chronicles, reprint sets generally do not affect tournament legality in supported formats; for example, cards reprinted in the Modern Masters reprint set, while legal for tournament play, did not necessarily cause the card to be included in the "Standard" environment. (If a card happened to be in Standard due to a separate reprinting, though, all "versions" of the card automatically become legal, including ones from a reprint set.)
These sets tend to be of two types: sets with a fixed deck buyers receive, and sets sold in randomized booster packs, similar to "normal" expansion sets, but only consisting of reprint cards. Chronicles, Premium Foil Booster, and sets of the Masters brand are printed in randomized boosters; others have a fixed card set.
