Feel like any current LS players that won will get a juiced up card. Not sure how many total there will be....first pack has a selection of 6, so if 2 sets maybe 12 total?:
LS Option: Judge (won as rookie + Set rookie HR record), Alonso (did same as Judge the next year), Cano (Father/son duo win), Harper (Won at home stadium), Cespedes (2x winner), Stanton (Generic power-hitter prototype throw in)
Legend Option: Prince Fielder reveal! (2x winner), Griffey Jr (3x winner) , Dave Parker (first HR Derby Champ), Frank Thomas, Cal Ripken Jr (Both legends with no high end card yet), Garret Anderson (low diamond collection reward only...so kind of another generic throw in to give him a high diamond option)
Possible legend sub: Morneau for his win against Hamilton who had a monster day but tired himself out at Yankee stadium
