The YuXin Football Megaminx (as it should be referred to by all non-americans) is a unique puzzle from YuXin, it is functionally the same as a megaminx but the pieces are coloured in a completely different way that makes the puzzle much more challenging to solve. There are some duplicate colours around the puzzle and you really need to just try it for yourself to fully understand how it works! Essentially, it has 32 faces but only 12 axes which I suspect is something that most cubers are definitely not used to. You can buy it here
