FINALLY GOT MY ATTACKY PACKS... Here's the collation I got in my 5 packs (in case anyone is keeping track):
L = LUDLOW, P=PUZZLE, FP = FULL PUZZLE PICTURE, CL = CHECKLIST, C = COUPON
2L, 8P, 14P, 5P, 10CL, 4P
11L, 13C, 3P, 10CL, 2P, 8P
13L, 7P, 12C, 1P, 15C, 6P
12L, 6P, 11C, 7P, 13C, 8P
15L, 14C, 5P, 11FP, 4P, 9P
So, I ended up with a full set of 15 common-back titles, 5 Luds, and zero sketch-cards.
I'm assuming that's fairly common?
