I believe one side of the S-foils(the side where the x wing's wings are folded together) decreases the primary value by one but gives them the ablility to then boost and maybe something else and then some way to flip the card, and on the other side you can prefrom talon rolls when you prefrom a turn and then some way to flip the card at the end of a phase.
