4. No Adam Page Vs. PAC
Ohh, remember when this was all over the news? One of the first rivalries created upon AEW's launch was between the surly "Bastard" and the stoic "Hangman". As far back as the ticket rally in February, Page vs. PAC was locked in for Double or Nothing.
Then shortly before the event, the match was suddenly scrapped. PAC was Dragon Gate's Open the Dream Gate champion, and the promotion didn't want PAC losing while still reigning with the gold. The match was thus pulled from the event, and Page won the Casino Battle Royale instead.
