Who would you like to see in the MCU?
Since Marvel managed to negotiate the film rights for Spider-Man, it feels like any character could be fair game (if you're confused: Marvel had to sell the film rights to a lot of their characters to avoid bankruptcy in the 90s).
The Russos apparently were gunning for the right to use Spider-Man in Civil War. Who would you like to see them fight for next? If it were between Deadpool and Wolverine, who would you pick?
