Official formats and tournament play have been an integral part of Magic
since its inception, ranging from casual-level events such as FNM
to the professional-level Pro Tour
and World Championships
. Organized play is headed by the DCI
, which provides game rules, tournament operating procedures, and other materials to private tournament organizers and players; it also operates a judge
certification program to provide consistent rules enforcement and promote fair play. The Judge Wiki
is probably the best place to look if one wants to get more involved with judging.
