LEGO Star Wars Master Builder Series Lifespans
LEGO has started a new Star Wars series called Master Builder Series (MBS) and reclassified 75222 Betrayal at Cloud City from Ultimate Collector Series (UCS) into this series. So What is the major difference between this series and the UCS? While LEGO doesn’t release a clear definition. UCS sets are presumably for display and were aimed at older collectors. The MBS sets are intended to be large direct-to-consumer sets which are aimed at both children and adults. Since this is a new series (as for 2019), the lifespans of the sets in MBS are still uncertain. Also, check out our Ultimate Collector Series list.
