Is this LEGO set a good investment?
“As a Nexo Knights set, 70321 LEGO General Magmar's Siege Machine of Doom is a good investment and has been slightly outperforming a typical Nexo Knights set with an average annual growth hovering around 9%. While not the best year over year return for this theme, it still is not a bad investment for collectors.”
Review brought to you by BrickEconomy Bot
“General Magmar's Siege Machine of Doom has a lot of action-packed surprises! Kids will have a blast launching the goblin discs and balls and transforming from vehicle mode to siege mode. The wheels and overall details are super edgy and fun. The LEGO Nexo Knights minifigures... More are sporting their signature armor and weapons. Kids will enjoy hours of imaginative, battle fun with this construction set.”

“General Magmar's Siege Machine of Doom is a great set. Not only does it have (2) great minifigures, but it is also very playable and looks nice, with a good selection of parts.”
The Brothers Brick
“As a decent playset and average parts pack, I think this set is better than the sum of its parts thanks to its size and heft, as well as the fact that it fills a much-need role in the Nexo Knights lineup. The Flama and General Magmar figs are standouts and, like 70324:... More Merlok's Library 2.0, it's improved greatly if you already own The Fortrex.”
