It's no big deal in terms of Token, I get 100 Token from association every season, so with the other free token the income is around 150 Token per season or more. And if I find a good player, I keep him for at least 7 or 8 seasons until I need to search for a new.
The hardest part is to see these players in the auctions. It's so time-consuming to look all day. Competition usually not very high, sometimes competition is good. When there are many people bidding on a 40% player I look at them if they are low level and have good players and platinum association. Then they know how to find good pieces with high market value and I will likely bid for a good player also. Then I might spend more than 5T also.
