And since they didn't announce the 4th member of Team Ciampa, being that Punk just returned and the show is in Chicago, they're going to have to pull a real surprise to have the crowd not get pissed it isn't Punk.
i thought it was dijak, riddle, keith lee, and ciampa?
e: oh wait riddle is gonna have a match with finn, i forgot lol
It's weird to leave that to a match time reveal, because it has to be huge or people are gonna shit on it. And there really aren't many options that could get the

reaction.
Garagno is on the shelf
Dream would get a good reaction and would make sense as the last time he was seen was losing the title to Strong, but I have no idea what his status is (still not clear if he's serving a Wellness suspension or has an injury, I believe it was reported as an injury but there have been no updates and he's been gone for 2 months, which would line up with a second Wellness suspension if rumors are to be believed)
CM Punk would be the ultimate reaction in Chicago but I can't imagine they're already asking him to get back in the ring and especially for something like that
To my knowledge there haven't been any big time indie star signings recently or any particularly big names that haven't made it to TV yet, and the Kushida/Swerve/Tyler Bate level guys seem like they'd be a let down as well. I would say Velveeta Dream would be the most logical and likely, but I don't actually know his status.
