*I didn't realize that an NPB draft ever had went nine rounds
Matsuka doesn't have many cards and what he does have appear to all be BBM cards. His rookie card is #486 in the 2005 1st Version set although he also appears in the 2005 Rookie Edition set (#80). His only other appearance in one of BBM's flagship sets is in the 2010 2nd Version set, where he shows up in the 1st Version update subset (#749). Most of his other cards are from the Baystars team sets from 2005 to 2009 and the Fighters team sets from 2010-2012. Two other cards of note - as one of the rare Tokyo University alumni to make it professionally in baseball, he shows up in both the insert set for the 2011 Tokyo Big Six Spring Version set that shows famous OB players for each team (#SP12) and the 2011 Legend Of Tokyo Big Six set (#099).
Here's the four cards of him that I have:
|2005 BBM Rookie Edition #80|
|2005 BBM 1st Version #486|
|2010 BBM 2nd Version #749|
|2011 BBM Legend Of Tokyo Big Six #099|
