Is a Summoner Skirmish considered a sanctioned event that requires a Head Judge?

Ruling: Yes, Summoner Skirmish is a sanctioned event and requires a Head Judge. Any event listed in the official events portal is considered sanctioned. If no dedicated judge is available, the event organizer or store manager serves as the Head Judge by default.

Nuances:

• Deck checks and registration are required at Skirmish level
• While technically the organizer can serve as Head Judge, it's strongly advisable to have someone knowledgeable in the rules present due to the competitive stakes and increased likelihood of judge calls
• Running a Skirmish without proper judging support may negatively impact the game's reputation at that store
