Jericho or Omega as the inaugural champion makes plenty of sense (hype, ratings, prestige for the belt, etc). Plenty of people in the Battle Royal that would make a viable opponent..MJF, Jimmy Havok, Joey Janela, maybe Darby Allin, maybe Hangman, maybe a bigger surprise. Whoever wins it, if they save the first Championship Match for AEW on TNT’s debut that puts that guy over as a top guy. And would no doubt be a great match.
My money is on Jericho being the first champ as well as possibly becoming IWGP champion and that being the thing that advances a NJPW partnership.
I think with the cards it’s a 21 card deck with 5 of each suit and a joker card.
The 5 guys who drew the same suit will be in the same group to either start the Battle Royal or be in the group of five that enters every three minutes. Whoever draws the joker is #21
