Without finding the actual cap, I can't say for 
sure... but I never saw any other Black 
Magician's, either, apart from Pandora's.

Pandora's Black Magician has beady dot eyes, 
marks around his eyes, and a mark on his chin. 
His hair sticks out from his hood, and his armor 
juts up. He has extra detail work on his chest, 
and his topmost shoulder plates jut upwards. 

Yugi's Black Magician has slightly more detailed 
eyes, no face markings, and his armor is square 
around the collar. His hair seems to stay inside 
his hood. His shoulder plates point the same 
direction.

From the scan, it looks like he has Pandora's 
BM's eye markings, hair, and chest plate; but he 
seems to have Yugi's BM's shoulder plates. So 
it's hard to tell. I didn't see Pandora's BM in 
that pose, but I was only watching on ff-mode.
