BBWs idea of blindly placing your pieces would be a pretty good idea. Could also do a multi shot game using only two amazons on each side and getting 2-3 shots per turn.

It could be where you get a reverse shot when you shot your arrow. It would go the reverse direction of your shot, the same number of squares. Unless you were against a wall in which case it wouldn't allow the second shot. Would make you watch where your shooting at so you didn't block yourself in.
