Here is my list. If anyone has any cards that contradict this chime in.
Grand Slammers:
Yellow/Green cards 1-12 without the 2 black lines on backs (some current image backs are incorrect)
Green/Blue cards 1-12 without the 2 black lines on backs (some current image backs are incorrect)
Red/Yellow cards 1-12 without the 2 black lines on backs (some current image backs are incorrect)
Purple/ Red cards 1-12 without the 2 black lines on backs PLUS cards 1-6 WITH the 2 black lines on backs (some current image backs need rearranging)
Purple cards 1-12 without the 2 black lines on backs PLUS cards 7-12 WITH the 2 black lines on backs (some current image backs need rearranging)
So to summarize adding 6 cards to each the purple & purple/red sets would cover all variations, If Admin wants the 5 current sets could be combined with A B C D E and sometimes F (12 cards) variations. I also suggest renaming the Purple to Blue/Purple. Then images need moving and or replacing.
