Playing the 7ball rail first is obviously the correct shot providing he can see the rail on the other side of the side pocket, however, I don't believe that would be the case or the Ghost wouldn't have put this position up for discussion. Lets say that the shooter can't see the rail to play the 7ball rail first..I agree tough spot.
Banking the 10ball looks to me like a very tough shot considering the distance and the thinness of the hit required to execute the shot, plus there's a kiss possibility if the shot is not struck well.:sorry Maybe it's not the time to shoot such a demanding shot, i'll save that shot and get back to it if I can't find anything I like better.
I really don't see any good options coming off the 10ball so i'm going to leave that ball alone as much as I don't want to do it, after all it's still a tough spot to be in and I really don't like coming off the 10ball. You have to defend against the 7ball return bank and you have accuracy problems if you try to bank it. I'll pass that shot for now, but like I said I may go back to it because it is doable but scary. I would like to further the 7ball in some way off the 8ball but there's nothing there that I like, pass that thought too. there's nothing available with coming off the 2ball or 9ball, so i'll cross those two balls off the menu. That leaves only the 13ball and 14ball to figure something out with, slim pickens. I can envision coming off the 13ball and hitting the rail before the 10ball with enough speed to position the cue ball around the score counter on the bottom rail. From there i'll take away the return bank on the 7ball..kinda..and hope to get back to the table. This option is very risky in two ways, even though there may be enough mass with the lined balls to deflect the cue ball to the rail in front of the 10ball it's marginal.

Plus you are going to leave a possible return bank with the 7ball if the shot is not executed well.

Not really in love with that shot either. That leaves the 14ball, and yes there is a shot coming off the 14ball that I like, i'll explain.
By hitting ..rail first.. before the 14ball thinly..I can then hit the side rail and go toward the 7ball with the cue ball and possibly land on top or very close to the 7ball or I can fall short of the 7ball on the side rail a foot short of the 7ball. Nothing wrong with landing there as well. There's a large margin for error with this shot so it plays very comfortably, and you don't leave any thing for your opponent to improve his position , or more importantly to run some balls off of.
My shot would be to go rail first off the 14ball, and settle for just getting out of trouble for the time being.
By the way, The Ghost must have played a good shot off the 2ball to put his opponent in a tough spot, just sayin.
