Lego (Danish: [ˈleːɡo];[1][2] stylised as LEGO) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colourful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways to construct objects including vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.[3][4]
If you don’t own Black Panther Pursuit or any of the sets that included Captain America, I guess it would a plus getting the both of them in this set but Super Heroes collectors tend to be completionists, so I think that scenario will be particularly rare. I guess you could always sell your spares on the secondary market, but really, who wants to do that?

Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.[73]
