When you have limited Tokens, don't bid in the first few days of the Season. Log on at odd hours to find when there are less bidders. And look at Hot Prospects, they are often a good value. This has worked for me on my 35T team, although it took me awhile to promote...

Even on teams where I farm Tokens I don't bid in the first few days.. too crazy. Actually not even on my main team (I buy Tokens for) I don't engage in bidding wars. I'd rather buy my Youth or wait a week in, truly.
