Here’s a look at the Winter Soldier and Captain America minifigures. Unfortunately, neither one of them is exclusive to this set, with this version of Winter Soldier making an appearance in 76047 Black Panther Pursuit. Captain America has been a lot more promiscuous, having made an appearance in 2 sets (Quinjet City Chase & Hydra Fortress Smash) and a polybag as well. His torso is also identical to the one from Black Panther Pursuit.
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.
