These are one-on-one games with 60 card minimums for the main deck (up to 15 card sideboard). Modern games should last average length for a game (about 20 minutes). With the exception of basic lands (Plains, Island, Swamp, Mountain, Forest, and Wastes), your combined deck and sideboard may not contain more than four of any individual card, counted by its English card title equivalent. This format includes powerful cards and strategies from the last two decades of Magic.
