  • Black Knight joins the Avengers
  • 1st unofficial team appearance of the Invaders: Captain America, Human Torch and Sub-Mariner
  • 💬 Bry's Outlook: this book has three desirable attributes - a great cover, the first appearance of the Invaders and the Black Knight joining the Avengers
  • I believe that once the Black Knight debuts in the Eternals or some post-credit scene hints at what's to come, there will be a lot of buyers jumping into the pool of all Keys related to the character
