Duelists' Convocation International

The Duelists' Convocation International (DCI) is the organization in charge of keeping up to date the Rankings of various collectible card games, mainly those produced by Wizards Of The Coast such as Magic: the Gathering and Pokémon.

The DCI is responsible for keeping these rankings up to date, which serve as the basis for determining the invitees to each of the national tournaments of these games, and the invitees to the Duelist Invitational, an invitation tournament in which the winner has as a prize to design a Magic: The Gathering card. The last 3 of these invitational tournaments were played online to promote this new way of playing the game.
