#4 & #3 Aleister Black and Humberto Carrillo

WWE has this reoccurring trope of Superstars coming to the rescue of Rey Mysterio and right now those two people are Aleister Black and Humberto Carrillo. While the storyline is a step up for Carrillo, and a way for Black to stay relevant, it could all be short-lived if Mysterio calls it quits.
In all honesty, the two Superstars are in a very important position right now and they need a satisfying conclusion in order to move forward. In fact, if Mysterio were to never compete again and the storyline between the two sides was to be dropped, it is obvious that Black and Carrillo would be among the worst off.

WWE is a game of momentum and staying relevant with the crowd. Unfortunately for Black and Carrillo, they have been spinning their wheels ever since Money in the Bank and losing this storyline would basically be the equivalent of starting over yet again.
