LEGO Master Builder Series

The LEGO Master Builder Series is a subtheme of LEGO Star Wars sets and a sister subtheme to the Ultimate Collector's Series. It was launched in 2018 with the release of 75222 Betrayal at Cloud City. While the Ultimate Collector's Series is more intended for display, the Master Builder Series—while retaining a complex building style—is meant more for play.
