9 of Ravenclaw: Gain
When the card is facing you: gratitude, luxury, self-sufficiency, culmination
When the card is facing away from you: over investment in work, financial setbacks
I chose Fluffly for this card mostly for the meanings behind the card when it's facing away from you, but I think there are a lot of reasons why the other side's meanings work as well and they are kind of intertwined. We don't know very much about Fluffy. He is only present in the first book and not very often. He belongs to Hagrid but he is placed in a room on the Third Floor to guard the entrance to the hiding place of the Philosopher's Stone. We meet him first when Harry is tricked by Draco Malfoy into being in a place he wasn't supposed to be that he could easily be caught in. Harry and his friends hide in the room that Fluffy is stationed in to guard to escape Filch and punishment if he finds them. It's an overestimation on the kids' side because they assumed that they could just hide in any room in Hogwarts. They were wrong because instead of an empty room, they were met with a growl-y, slobbery Fluffy who isn't really as safe as Hagrid says he is.
Secrecy at Hogwarts is overestimated when it comes to Fluffy. It was not as hard as it should have been for Hagrid to let slip the way to get past Fluffy to a stranger (Quirrel/Voldemort) in a bar. This therefore leads to the overestimation of Fluffy's actual ability to guard. The fact that Voldemort is able to get through Fluffy so easily and be one step closer to the Philosopher's Stone is pretty scary. Not to mention that Harry, Ron, and Hermione end up also being able to get past Fluffy. Obviously it was a bit silly of someone to think that a three headed dog who gets sleepy when listening to music was a good first obstacle for someone in pursuit of the Philosopher's Stone.
Luxury is a pretty weird thing to connect Fluffy to, but I think it works. The way you get past Fluffy is by playing music for him that makes him fall asleep. Music can be considered a luxury. Self sufficiency is a little easier to connect and also has both a good side and a bad side. In order to get past Fluffy, you need to be self-sufficient, meaning you need to have the ability to play music. This applies to everyone, from Voldemort to Harry. Also Voldemort had to be self sufficient to get the information on how to get past Fluffy. He figured out a way to be unrecognizable and get Hagrid drunk enough to reveal the secret. For gratitude, I want to connect Fluffy to this by saying that Hagid loved him and cared for him. I think that also Hagrid might have been grateful to Dumbledore for letting him guard something special with one of his magical creatures.
