The Blackless "set" is check listed (396) in several sources and does include IA cards ( any and all cards from sheets A, B and C ). None of the CLs in the 82 set are on the A,B and C sheets. Some are on the D sheet and one seller has offered some Blackless cards from the D sheet but it is unclear if all cards on that sheet can be found that way or if the condition is recurring.
