#3 Current AEW wrestler MJF

Current AEW star MJF is considered by many to be one of the brightest stars currently on the All Elite Wrestling roster.
Despite his tender age, MJF has quickly established himself as one of the best promo-cutters in AEW today. He has further backed this up with excellent rivalries against Cody Rhodes, Jon Moxley and Chris Jericho.
MJF is still engaged in his feud with Chris Jericho, forcing Le Champion to complete the "Five Labors of Jericho" weekly on Dynamite, leading to a match between the two at "All Out' in September.
Should CM Punk become "All Elite," MJF's ego won't allow the former WWE World Heavyweight Champion to take the spotlight away from himself. Therefore it's completely plausible that MJF and The Pinnacle could interrupt CM Punk's debut.
This would then possibly lead to inevitable matches between MJF and CM Punk inside an AEW ring in the future.
