It generally depends on how many tokens you have and how much money you have. I generally run with the team I already have until the major bidding wars are over and if my current team is not good enough then I myself to a poor season and start to build for the next season. I am not one of those players that have to win everything every season. I am careful with my tokens and will not bid more than 3 for any player unless I am absolutely desprerate. At your level tokens and money are hard to come by unless you invest your own money, so be careful with your bidding.
