#3 Aleister Black
Aleister Black has had a string of impressive victories lately and while some might think it's too early to put him in the title picture, the names he has beaten says otherwise. Beyond all that, Black's highflying style would match perfectly with the viciousness of Nakamura, which should make for an interesting feud.
It would also be a great way for WWE to finally move Black up the ladder a bit and get him out of these one-time feuds with established midcard talent. At least that way, WWE is keeping the storyline fresh and building tension, while also getting fans to rally behind Black as a midcard anti-hero.
In the end, that might not sound like much, but a win against Nakamura would be a great way to start proving that this is one of the future stars of WWE. Sure, it comes at the expense of Nakamura, who hasn't been Interconetnal champion for very long, but it would honestly be justified if it helps build a Superstar like Black.
