Warleson Oliveira’s take on the traditional card game, Uno, is one appreciated by many fans of the game. It’s a simple and beautiful design which many have compared to it as a “dark mode” version of the game. Mattel is known for creating many variations of Uno. Many fans have asked where to get these designed cards. If we can get enough people to support this design, we can get Mattel’s attention and Warleson can make a deal to get these cards into production.
