I am goin to say Royals!!
They could(or rather should) have made more moves but they have done really well with what they had to start with. Royals now have a legitimate 1b and definetly opened up some room on the roster for our prospects down in the minors. While the royals have sold off alot of players we now have some decent pitchin prospects that I am waitin for hell one of em already won a game. I like the moves that we have made for the future with some home grown players. We definetly filled some NEEDED holes in our team while creatin a lot of new ones in the bullpen. Time will tell!!
Will not start an arguement but the yankees .

comin from a man who watches a "poor" team all the time.
Edit if not royals then I think the dodgers did pretty well with their last day of tradin. Maddux isnt what he used to be but it is still something and lugo is a great player. Totally forgot about them wow my bad.
