#2 Aiden English

Aiden English, one of the WWE's most talented Superstars, is currently involved in an angle with Rusev and Lana; costing them matches every week on SmackDown. What if after this feud he moves over to singles competition, and continues his gimmick of portraying a great singer, while taking a dig at Elias?
That, in turn, could serve to ignite a rivalry between English and Elias--which would be one for the ages! English is not only great on the mic, but also skilled in the mat-wrestling department.

Meanwhile, Elias always seems to cut fiery promos, besides possessing great athletic ability as well.
For those unaware, both English and Elias are legitimately trained musicians; with the former having extensively studied the art of stage combat--an art which requires the performer to optimally act, sing as well as engage in simulated combat.
Elias could respond to English's taunts on RAW, and they can have a face-off on either brand, thus leading to a feud between them. This one would likely be a musical rivalry which would undoubtedly be unparalleled in the professional wrestling world.
