Kenny Omega...Philly is pretty smarky and bullet club is still pretty hot.

Bzzzz
But seriously, it's Punk just because I think everyone who was hoping he'd be back by now probably gave up hope a long time ago. Plus the Rumble brings out the smarks and they're in Philly in 2018 so it's just one big combo of everything that would have everyone lose their shyt.
Kenny omega would be fire but that's not gonna happen.
Punk would be amazing. Again tho, not happening.
Cena or Shane could get brazy pops if they stayed off TV till then. HHH too, though he'd have no real reason to enter.
