I don't know how good this will turn out to be, but I wanted to point out that the art changes from the original on these upgraded cards; apparently 3 XP buys you a little shot glass ( survivors just get more whiskey).
The main changes here are the addition of the fast trait, an extra +1 on the defensive buff, making your molotov cocktail attack deal +1 damage, and the card has a icon in case you're in to pitching your XP cards for checks.
I can see an argument for Jenny Barnes taking this at some point because miss moneybags plays it easily, hits 6s on her stats, and it represents a nice slot-free attack that leaves her hands free for her guns or Lockpicks or wotnot.
I tried Tennessee Sour Mash in Finn Edwards and have been mostly unimpressed, although it is another illicit card to search out or recur with Smuggled Goods. The small changes here just don't feel worthy of 3 XP that could be better spent on a Lola Santiago or something.
