Khans of Tarkir is part of the Khans of Tarkir block, which is Large-Small-Large with a unique draft structure (the small set is drafted with both large sets, but the large sets are never drafted together) and a time traveling element. The draft structure is the first thing from which Khans of Tarkir set was built.
Khans of Tarkir contains 269 cards (20 basic lands, 101 commons, 80 uncommons, 53 rares, 15 mythic rares), and includes randomly inserted premium versions of all cards. It is also the first set since Dragon’s Maze to not have any Dragon creature cards. The expansion symbol depicts crossed swords on a shield, similar to the symbol of Legions.
