This subtheme is based on Ninjago Season 10, March of the Oni and is the third part of the Oni Trilogy. This was the first and only season not to have a full set wave accompany the season. The Ninjago Accessory set was the only set made for season ten, and, it is a minifigure pack, not a full set.
2019 LEGO Sets
There were a number of events in 2019 that helped shaped the investment market for LEGO. Probably the most important event is that LEGO Star Wars celebrated its 20th anniversary. In addition, LEGO released new themes such as Hidden Side, Overwatch and a set based on the Netflix series Stranger Things. Sadly the Nexo Knights and Elves themes were discontinued in 2019.
