text: As soon as there are no permanents with space sculptor on the battlefield, all sector assignments are lost. Notably, this means that if Space Beleren’s +1 ability has been activated earlier in the turn, creatures are no longer restricted from blocking, so watch out! If another (or the same) Space Beleren returns to the battlefield, creatures on the battlefield at that time will once again be assigned to sectors, but their new sector assignments are not influenced by any previous sector assignments they may have had.
