I've had the idea before- a feature that lets a manager "sponsor" a match to encourage more fan support. There's the Send Thanks feature after the match; my idea would be manager can pay a token fee before a match, and other managers who come to support have a chance to win some prize, like an extra green pack or pack trio, or different options at 1,3,5 sponsor tokens for example. 5 fans support your team, each have a 1/5 chance to win. Sponsored matches would advertise ahead of match time and have an icon to signify the special prize.
Pretty simple idea, but easy to implement, another token source for Nordeus.
