#4 Aleister Black

Aleister Black has been looking for credible opponents to take on for quite some time, and since his move to SmackDown has taken out both Cesaro and Sami Zayn.
While both Zayn and Cesaro belong to the RAW brand, the wildcard rule allowed them to travel to SmackDown to take on Black. Similarly, Corbin will find himself in Black’s den as he takes the stage on SmackDown for his King Of The Ring coronation ceremony.

We haven’t seen Black since before SummerSlam and he wasn’t given an opportunity to participate in the King of the Ring tournament. Therefore, we can possibly see him interrupt and attack the heelish Corbin in an attempt to prove that he’s the best wrestler who’s battled on NXT, RAW, and SmackDown.
Putting Black and Corbin in a feud could prove to be fruitful in the long run. While the King of the Ring title is currently non-transferable, a win for Black over the current King of the Ring could help him get more attention and allow him to continue his climb up the rankings on SmackDown LIVE.
