Here's my post from the other forum:

Ever since I killed a 15th series box years ago I have known that there are certain exceptions to the
standard Knight's Move collation of stickers within an original series unopened pack.
The exceptions invariably involve stickers on one edge of the sheet or the other.
In the 15th series box I recorded these exceptions:
Jerkitol/Electric Slave (Electric Slave on right edge of sheet)
Soremel/Dynamites (Dynamites on right edge)
Mashbox/View Monster (View Monster on right edge)
Earth Barn/Mashbox (Earth Barn on left edge)
Fearout/Cheapstick (Fearout on left edge)
Fang Edward/Smell-Ecch (Fang Edward on left edge)
Earth Barn/Dynamites (both stickers on edges)
I broke the above into groups based on the relative positions.
See the sheet to understand:
I happened to have a low grade 8th series pack lying around showing
Rolaches (on the right edge), so I killed it and sure enough it
contained Biva (similar to the group of three above).
I would love to kill tons of boxes to investigate this further, but
as of now I would say that packs containing at least one sticker
from the edge of the sheet may be legitimate and not obey a knight's
move arrangement. It is likely to occur in a way similar to the ones
described above.
