#2 Anybody from IMPACT/NJPW/AAA could show up in the AEW Casino Battle Royale
An appearance from an IMPACT, NJPW, or AAA talent would certainly send shockwaves across the industry. AEW has opened the forbidden door to many promotions. Several companies currently work together by trading their talent back and forth.
IMPACT Wrestling star Sami Callihan could prove to be a mystery entrant in the upcoming Battle Royale. He recently interjected himself during an Omega-Moose confrontation, making it clear that he is coming after Kenny Omega.

A potential Battle Royale win could be surprising, but it will give us a great inter-promotion main event in the form of Kenny Omega vs. Sami Callihan.
Similarly, Andrade from AAA could show up as a mystery entrant in the Casino Battle Royale. Ever since the Mexican star parted ways with WWE, he has made it clear that he wants to win the AAA Mega Championship from Kenny Omega and bring the title back to Mexico.
Even Dave Meltzer of the Wrestling Observer Newsletter stated that the match between Omega-Andrade is in the works for TripleMania 29 this year.
AEW could surprise their fanbase by having Andrade win Casino Battle Royale this Sunday and face Omega for both the AAA and AEW Championships down the line.
NJPW legend Yuji Nagata recently returned to TNT programming after more than twenty years. He may appear at Double or Nothing if AEW allows him to compete in the Casino Battle Royale. Nagata's presence in the match will be huge for AEW.
It's safe to say that if any wrestler from a different promotion appears at Sunday's pay-per-view, it will most likely be a win-win situation for everybody involved, regardless of the result.
