Could be any cosmetic: BP skins, Buddies, sprays , cards , etc. What is that one cosmetic that you would buy in a heartbeat? For me it's the Unstoppable - Viper card. Sadly, i couldn't play a lot during the season it was released and as a viper main, it hurts seeing someone else use it. I know it won't come back ( BP skin) but a guy can hope.
