Les cinq cartes Anafenza, the Foremost, Narset, Enlightened Master, Sidisi, Brood Tyrant, Zurgo Helmsmasher et Surrak Dragonclaw, de l'édition Khans of Tarkir, forment un cycle de créatures légendaires tricolores, chacune représentant le khan de son clan.
Au moment des événements de l'édition Tarkir: Dragonstorm, les khans des clans sont respectivement Felothar, Dawn of the Abzan, Narset, Jeskai Waymaster, Kotis, the Fangkeeper, Zurgo, Thunder's Decree et Eshki Dragonclaw ; les anciens khans Anafenza, Unyielding Lineage, Sidisi, Regent of the Mire et Surrak, Elusive Hunter ont une autre occupation au sein du clan.

Source 1 (Prose and Khans) - Source 2 (Defined clans - "Once we had five clans, we had to have a more balanced structure to match the color pie. Shards of Alara focused on three-color shards (a color and its two allies), but we'd never done a wedge-focused set (a color and its two enemies).") - Source 3 (Use of Multicolor - Legendary Wedge Creatures (Mythic Rare) - "[...] The set needs mythic rare warlords, and the clans are each three colors. This cycle of mythic rare legendary creatures was a no-brainer. [...] These were the leaders of each clan.")
