Set Information

Khans of Tarkir (KTK) will be the first set of the Khans block. It is set on Tarkir, the home plane of famous Planeswalker Sarkhan Vol. Tarkir is ruled by five different and rivaling clans, each of which ruled by a Khan. A major role in the set will be given to dragons, which are extinct on Tarkir but to which all clans are deeply devoted. Clans represent the so called wedges (similar to the shards in Shards of Alara):
