#4.) Austin Aries
Who other to have wrestle on "All-in" than the greatest man who ever lived, Austin Aries. Aries currently holds the Impact World championship, IPW World championship, Defiant World Championship, and WSW championship. Since being released from the WWE in September, Aries has been on a tear winning championships at almost every promotion he has stepped in. With a rivalry with Marty Scrull at Defiant Wrestling, a rematch between these two would be a great match for the crowd and having Aries defend one of his championships would be a great layer to add to "All-In" Card!
