Depends how "open" you are talking. AL games are very open (subject to the +1 rule) with a few limits based on the very open standards of FR and Ebberon. I would be more hesitant to run something like Theros open table due to the restrictions the setting places both thematically and racially.That seems like a perfectly fine attitude to have in a home game with a fixed roster of players and a not terribly practical one in an open table game with a rotating roster.
