This is the only card which gives search ability for . Additionally, I think that this is the most powerful searching cards in AHLCG. Of course, No Stone Unturned could search entire deck, but NSU5 is event card, so that you only can play once per deck. However, Lucky Cigarette Case is asset card, so you can search once per round. Nevertheless, the number of cards you can search is large. In many cases, you could search at least 3~6 cards. I usually told that / has leak of searching tools, and that's the shortage of those factions; this is not true for now, due to this card.
Let me introduce strange combo. With LCC3, you could draw and use your powerful cards in your deck. After your deck only contains unnecessary cards, you can commit Daredevil. Then, your whole deck is dicarded. To do that, you need to remove skill cards (not all, but 1 icon only). Addtionally, your deck includes at most 1 weakness; you could discard 1 weakness in your deck by Daredevil. Generally, your deck contains 2 weakness cards, so you should resolve 1 weakness. However, Jenny doesn't need to do, since her signature weakness is attached to a location so that you don't consider it in the middle of the game.
