Ultimate Collector’s Series vs. Master Builder Series

LEGO® Ultimate Collector Series sets are detailed, unique and challenging models meant for display. A collector’s display card is included with each set.

The Master Builder Series kicks off with the release of 75222 Betrayal at Cloud City™. Master Builders Series sets, like the Ultimate Collector’s Series sets, are complex builds; however, they’re built with the play aspect in mind, having many play features, functions and interior details.
