Here are my four variations. I have found that the best way to determine the clipped 'B' versions is to look to the lower right portion of the circle (I highlighted it on the card in the bottom row) to find the 'colorless arc,' as I call it.
It's also worth noting that in the regular version of both the 'playing card' and 'playing card game' variations, there is often a tiny, hairline occurrence of this 'colorless arc.' Here, it is seen in the bottom left 'playing card game' card. (In Al's post #10, you can see it in his 'playing card' version at top left.)
