I wonder if this should be put in a the clever pool. Raven does have some traits of a dark magical girl.
Not really, this image doesn't contain the context of Raven being a magical girl, even if she is indeed a girl who can use magic. This is just a generic crossover image like every other ones without any visual implications of any connections worthy of the 'clever' pool.
Otherwise all the Saber-Sayaka images would qualify for the clever pool too.
Really, anything with [sensibly proportioned] Raven (and/or Starfire) in it is just tasty. Some of those childhood characters that I knew I liked a bit too much before I knew what I was thinking...but I know now.
