Lockpicks is a very strong card. We don't really need to dicuss this. Winifred Habbamock, Finn Edwards and Trish Scarborough all just get to go at it for eight (while Bob Jenkins at least gets to go to 7), which should be enough to beat the bag in most scenarios, at least at Normal difficulty.
What's more is that it synergizes greatly with Lucky Cigarette Case and its level 3 option. These two cards in tandem basically form an engine that lets you go really hard. Digging 2-4 cards to draw one and find a clue every turn is going to propel you through a scenario very efficiently.
Worth mentioning, too, is that someone like Lola Santiago or Gené Beauregard give you a boost on both numbers, effectively boosting your tests to 10 on the aforementioned characters. At this point, the engine gets a little XP-intensive, but still: This card isn't outright powerful in the way that other cards are, but it's incredibly consistent.
Along with Thieves' Kit and the rogue events like Intel Report and Pilfer, this card can turn your mobile rogue into a clue finding machine that has both consistency and explosiveness, which is just a fun playstyle to me. Where this card really shines is in True Solo, where a lot of your locations consistently only ask you to find one clue, so the exhaust often isn't that much of a downside if you manage to weave a lower shroud location into your patterns that you can crack with your base book.
