Theres not that many ways to get Black Stallions compared to several other items in game prize pools that are no longer wanted so much or worth anything. Catnip, Great Tit, Red cock, etc. They're also not too important or needed in any of the current game mechanics/ desire of players, whereas Black stallions sort of are (and are being milked for profit. Theres tons unlisted atm and i'm not the only one that needs/wants stallys.) So i suggest they be added to more games as a prize, or replace the likes of catnip in a couple of games since theres a huge abundance of catnip anyway.
