Is Riot a rare skin?

Excuse me, could you please clarify if the term 'Riot' being referred to here is in the context of a rare skin in a particular game or platform? If so, it would be helpful to know which game or platform you're talking about, as the rarity of skins can vary greatly depending on the game and its community. For example, some games have a clear definition of what constitutes a rare skin, while others may have a more subjective evaluation. Without this context, it's difficult to definitively state whether 'Riot' is considered a rare skin or not.
