Modern is a constructed format that allows expansion sets and core sets from Eighth Edition forward, save for the Modern ban list. The modern format thus encompasses all cards that have been printed in a core or expansion set using the modern card frame (plus some others from Time Spiral)
The format was introduced as a non-sanctioned Magic Online format in May, 19, 2011 and subsequently officially codified on August 12, 2011, when the format of Pro Tour Philadelphia was changed from Extended to Modern.
Constructed decks must contain a minimum of sixty cards. There is no maximum deck size; however, you must be able to shuffle your deck with no assistance. Like other constructed formats, a sideboard of at most fifteen cards can be used.
With the exception of basic lands (land cards that have the “basic” supertype) and cards like Relentless Rats, a player’s combined deck and sideboard may not contain more than four of any individual card, counted by its English card title equivalent.
