Amanda wants upgraded perception and deduction in her deck. The problem is, even with practice makes perfect, you can only play these cards so many times. ... so why not use obscure studies to loop them? Play them twice, then use obscure studies to put deduction(2) back in your hand. If you’re feeling frisky, or have control of the encounter deck (teaming with Gloria for example, or people with First Watch), You could even use your favorite skill card three times before replacing it. If you’re finishing up clues in a scenario, five uses of deduction(2) should do it for you, even if you miss a few times. Consider Cryptographic Cipher also gives you a fast action.

Another use of studies is to get rid of your weakness! The forced effect of whispers takes place at the beginning of a turn, so as long as you can apply whispers to a skill check before next round, you can get rid of it.

This is a great example of a signature asset. It's simple. It enhances exactly what the investigator wants to do. I guess the one question is timing. Do you hold this in your hand until you draw a really crap card during your special action, or do you try to get it out and have a 5/5/5/5 turn ASAP? It's probably worth noting that there aren't a lot of reliable* cards out there, so if you're going toi have one versatile turn, this is going to be it.

• Note: I said reliable -- Inquiring Mind relies on clues, Promise of Power puts curses in the bag, etc. And is it really worth committing The Necronomicon?
