It's not as bad as it looks, really.
Let me explain!
class characters usually rely on maximized hit chances with lots of cash-money and cards committed to ensure success and high-profile results. You don't take a .41 Derringer or any of the other (Non Chicago Typewriter) weapons into a fight check without doing everything to ensure a successful check. If you want to do careless fight checks just 2 above the target then play a instead! attacks are all about doubling up and dealing big and powerful hits where only the fails your attack. On these attacks it really, really doesn't matter if the enemy gets buffed with Retaliate or not, it really doesn't.
Also, Retaliate gets shut off if the enemy is exhausted, in these circumstances Knuckleduster suddenly becomes a cheap shot weapon, Finn Edwards evades all the foes anyway, even if he doesn't immediately need to, quite often you'll find yourself Evading a foe, punching him once, then clearing out, then once that foe gets in your way again down the line he'll have some damage on him and be easier to kill.
Suffice to say that I've really changed my mind about this card after actually trying it. Don't be delusional though, Switchblade is still a far-superior "infinite" weapon.
