I think this card is incredibly broken. When I first saw it, I thought the skill test had to be succesful in order to get the bonus, which would 've been totally reasonable if that were the case. Instead, Survivors now get a card that lets them click for 2 resources once a turn simply by taking an investigate action and using this card and they still have a chance to get a clue. The only downsides I see are when there are negative effects of failing on certain tokens and the negative effects on Haunted locations in TCU. Other than that, I think it's almost an auto-include in non-Dark Horse decks in every Survivor.
What makes this card even better is its notable interaction with Rabbit's Foot and especially its upgraded version. With Rabbit's Foot, you now have even more reasons to fail tests, as you can now click for 2 resources and a card, and what makes this card totally absurd is its combination with Rabbit's Foot (3): With it, you can take an investigate action, proc Drawing Thin to increase the difficulty of the test, fail hard and tutor even further than you otherwise would, plus you get resources for doing so! And you can do this every turn! So, you now have a powerful tutoring engine that can get you all the cards you need while making money in the process!! Absolutely unreal!!
But you won't always have the luxury to draw or make money, right? Sometimes there's a tight race against the agenda, or the situation is rough and you don't have the luxury to juggle around with your deck. So, let's find situations where this is useful in other ways, namely when you have the opportunity to use this during a test you want to pass. These tests are not very common, but such situations can arise and allow you to make more profit out of this card. An example that comes in mind is a Finn Edwards or Wendy Adams with Lockpicks. Both of these characters can use Lockpicks to investigate at high skill value, allowing the use of Drawing Thin during that investigation without failing the test. In the same manner, other cards that test more than one stat that add up to one another can make interesting cases. Some examples are Cheap Shot and Slip Away. Another example is Rita Young. With her high Agility and all those assets that boost it further she has a good chance to pass an evade test even if its increased by 2. But let's be honest, if you have this card early, you can always just click for 2 resources and those cases where you will want to make money during a skill test will be rare, so it's a win-win in most situations.
Don't get me wrong. It's not that I don't like card. I love it, to be honest. But I wonder; how is it possible that a card with such powerful abilities and interactions was released?? Simply amazing...
