I think it works pretty well. We're playing with the gold general being the demoted value and the silver general being the promoted value, correct? I just want to make sure the gold general was intentional since you have the gold general being the promoted value in your notes on the right.
I'm fine with leaving the lion out of it for now. If we want to add it, or another piece, back in, we can put it on the square in front of the ramshead soldier since the RS jumps over that square anyway.
Let's test it, shall we?
