Sì, il TO (o l'arbitro) può giocare ad un suo torneo se rispetta le seguenti regole:
Magic Tournament Rules ha scritto:
Tournament officials may play in a DCI-sanctioned tournament for which they are a tournament official if (and only if) the tournament is of the following event types:
• Friday Night Magic
• Prerelease
• Launch Party
• Magic Game Day
• Other non-Premier Magic Tournaments
• Tournaments in which the official Wizards of the Coast tournament fact sheet specifically permits officials of that tournament to play
If one or more tournament officials play in the tournament, it must be run at Regular REL. If tournament officials play in the tournament and the tournament is not one of the allowed event types listed above, the tournament will be invalidated. Tournament officials are required to officiate tournaments fairly and without regard to their own self-interest.
Tra i tornei in cui arbitri e TO non possono giocare ci sono anche le tappe del campionato cittadino.
