Big hitter card. An autofail token can ruin the most assured of hits and this is that tech card you include so that your once-in-a-scenario Double Vicious Blow + Lightning Gun combo assuredly hits.
More realistically though its gonna be a single Vicious Blow with a .45 Automatic to deal that imperative 3 damage hit to a Ravenous Ghoul or a Vicious Blow + .45 Automatic to kill one of oh-so many 4hp foes that terrorize our mythos decks.
This latter scenario is probably the most common and useful use of "Eat lead!" in this game, to ensure that those moderately tough "minibosses" die in as few actions and as little risk as possible.
