Fall Guy isn't that attractive to me, but then again I've never liked cards specifically aimed at mitigating a losing position. I'd rather put in some other cards that help me fight harder and maybe be winning instead.
This. If you're having trouble with either terror or combat struggles to the point where you think you need a slot in your deck that's only purpose is to commit seppuku to save you from them, maybe look at some of Syndicate's other options to turn things in your favor. Lena is a 1 drop that can help turn icons in your favor. Pit Boss can give you willpower. There are options to make opponent's icons not count or change them into skill struggles. This is Syndicate we're talking about! If you can't win, change the rules.
Since I'm thumbing my nose at all your picks, I guess it's only fair that I post my personal top 10 so you all can play turnabout. So in no particular order:
O'Bannion's Inner Council
On The Lam
MR. David Pan
Clover Club Pit Boss
Hanyatl's 12:3 (My controversial pick)
Honorable mention: Clover Club Torch Singer (alt art version or gtfo), Henry Knoll, Dutch Courage
