Team Fortress 2 - “Blind-Box-icorns”

Unfinished pitch/concept I made a couple of years back of exploring the possibilities of where a Balloonicorn’s design can go. Team Fortress 2 already has merchandised blind boxes for the main merc lineup, but what if there was a series solely for the Balloonicorn? 
Featuring what would be the red and blu skins for possible unboxing, there would be uncommon and rare tiers of Balloonicorn skins, as well. Some fetching fashion tips from characters and npcs, to game elements such as Scream Fortress’ bonus ducks. 
The vinyls could have special features, based on rarity: 
- Glow-in-the-dark elements 
- Special materials, such as fake vinyl gold, or opaque parts 
Box details could look like TF2 gift boxes, with info on the sides such as series and Balloonicorn odds. Box mock-up possibly coming soon, if I find time for this old project again.
