Everyone company eventually does their own version of a WWE staple like The Rumble or KOTR, so I hope AEW does the same.
I loved Lucha Underground. They introduced their own "mid card" title called the Gift of the Gods Championship. It was a match where you had 7 medallions, and once all 7 medallions were held by by an individual person, those 7 people would then compete in a big match all at once to determine who would be champion.
The Championship even had like magnets in it to keep the medallions in place. And once someone had the title, they could "cash in" the championship for a World Title Shot. Now, I don't know if this would work for AEW with their ranking system. But I think it's a super creative idea. And I want to see someone else use it.
LU also had their version of the Rumble called Aztec Warfare where you would have guys come in 1 at a time but it was pin fall and submission based as opposed to throwing people over the top rope.
If you haven't figured me out, I really miss Lucha Underground
But the point is, you can take a concept like MITB or the Rumble and make it really unique and interesting. And I hope AEW does the same. And hopefull it goes better than their first new idea that Casino Battle Royale, because that hasn't clicked for me.
