Flight of spies: Up to two heroes may retreat unharmed you may return a good enhancement to hand.
I use any battle winner that would result in his hero being removed from battle (discard capture etc.) can he play flight of spies? I know someone who is of the opinion that it will protect himself. He simply does RA then if I play a battle winner he uses FoS to save his hero and then returns FoS to his hand. I don't think it works because it doesn't have an interrupt. You can't have immunity after the fact. I think he treats it as an instead almost. Instead of X return heroes to territory and one good enhancement. If he's right (which I don't think he is) then this card is absurdly good. No matter what cards you have you aren't risking your hero.
Thoughts?
Thanks again in advance.

Flight of Spies can only be played if you have regular initiative, or if played via a "play" ability. If the opponent plays a battle winner, you cannot play Flight of Spies by itself since it doesn't interrupt or negate anything. You could use an "interrupt, play next" card and then play Flight of Spies, but FoS cannot be used during special initiative otherwise.
