Two Cubs made the list, Ernie Banks (his 500th Home Run) and Starlin Castro (two hits on June 14, 2012 to help the Cubs beat the Brewers in extra innings).
Mr. Cub and the Hawk (fresh from being pulled out of the ivy) were included.
Ryne Sandberg is in this subset, but I wouldn't exactly call Larry Bowa and Ryne Sandberg for Ivan DeJesus a blockbuster trade. It was Dallas Green looking for a field leader (Bowa) and getting a prospect, too (Sandberg) while the Phillies got a younger shortstop with better range.
Ryan Dempster is in the base update set as a Ranger, but the minis must be printed much earlier, so he's still with the Cubs. Bryan LaHair got the mini set as a consolation prize instead of an All Star card.
