In LOW OPL Nexus Night events where the LGS/organizer does not require deck registration or decklist submission, can players change decks between rounds?

Ruling: The rules regarding changing decks between rounds are completely up to the LGS and the participants to decide.

Nuances:

• This applies specifically to Nexus Night events which are described as casual event types
• Different stores may have different policies even within the same event format
• Some judges may still expect players to use the same deck throughout even without deck registration requirements
