Finally a card to dump an otherwise unused . How often did I draw an when playing Zoey Samaras and felt betrayed by the chaos back, because I was testing on a Willpower treachery and not on a fight check. Countless time I drew the when playing Ursula Downs and quitly thought "Okay, I have a free move, if I would only need to move right now, which I don't". Any Investigator with a pretty situational effect should consider this. It is Chaos Bag control at its best. It is absolutely worth 5xp to me.
The Black Cat
A Liar, or a Prophet, or Both
Ally. Avatar. Dreamlands.
Anytime you reveal a , , or symbol during a skill test, you may choose to use the following effects instead of that symbol's normal effects:
: -1. The Black Cat takes 1 direct damage.
: -1. The Black Cat takes 1 direct horror.
: +5. Heal all damage and horror from The Black Cat.

Expensive, but absolutely worth it. Jim Culver in particular loves this cat, as it provides protection against a good chunk of the chaos bag when combined with his ability (plus his elder sign isn't so hot anyway). At 3/3 health/sanity and only two resources it also works well as a sturdy shield that has the potential to heal itself.
Every investigator can try to pet The Cat. Who does not appreciate a 3/3 soak, especially by the end of a tough campaign? But the XP cost is too high for just a soak and some, rather random, help on the road. If only you could mess with the chaos bag enough to take advantage of the upgraded modifiers The Cat brings?
Enter Jacqueline Fine. Even without Olive McBride and Charisma, even without Grotesque Statue she has much bigger chance to draw one of the tokens The Black Cat cares about.
A psychic should run a Sixth Sense, trying to fish symbol tokens (fish for a squid?) - but by the end of the campaign, these happen to be quite ugly and sometimes force you to make unpleasant decisions - The Cat fixes the problem! Even when Shrivelling someone, it's better to take a horror while passing a test rather than wasting a charge, failing a test, being punched back AND taking a horror.
Jacqueline's is something you like to ignore if you can, but if you need to use it, at least it can do something charitable - like healing The Cat!
Furthermore with The Cat by her side (on her shoulder?), Dark Future is much less of a problem, significantly decreasing the risk of Jacqueline's ending in fails with terrible consequences.
A new niche to the Cat could be Butterfly Swords Lily Chen.
Why her?
The reason is rather simple: the Swords make pull 2 tokens per attack and therefore this is that many more chances to pull a Symbol token that often results in very sad outcomes especially in Hard/Expert.
The cat mitigates this risk.
To make the best out of it, attach 2 Trusted to the cat, if you're really pushy you can get The Star • XVII and let the cat do his job. Then with all these tokens, you will eventually find the that you probably wouldn't have used as most of the time your Disciplines are Unbroken.
I ran the Black Cat with Charlie Kane and had some fantastic moments. The double Wilds give a +3 to any 1 test, possibly another with inspiring presence or Bonnie. Here are some more words to complete this review.
