I'm gonna throw down Kitty or (and this is a curve ball) Mystique for the Silhouette Guesser - HARD maybe on Wanda or Polaris, mostly due to how weird it'd be to introduce them before the other two in general imo.
I feel like Magik and Psylocke are too well-associated with straight hair to break too far from that branding compared to what was shown, and conversely the hair isn't floofy ENOUGH to be Dazzler in my mind.
We'll see thou, and I look forward to it either way! And praying the third is Jubes.
