Bid on older players 30+ with Special ability they are ex-scouts, they are underestimated from people and usually you are getting them with 1 token, most of them are performing very well formwise, you can have a full squad of 5* with 11 tokens for all season, next season do the same, no need for tanking or biding do the same even for injurie replacemert, thats what i think its better if you are short on tokens.
