Stat Anomaly, 20 Losses in a Season List

Here is the list of base cards that would showcase the 20 losses in a season statline. I will trade for any of these. I realize this will be a difficult path, but there's only 40 cards. The goal is to get them all by the end of 2010. Any suggestions on how to go about searching for them?
