#3 Finn Balor
A Finn Balor-Dean Ambrose feud has somehow eluded the fans. Apart from a few multi-man matches, they never crossed paths.
If they had fought one-to-one, it could have served as a spot for the Intercontinental Championship at WrestleMania 35 - the workhorse title involving two of WWE's most reliable superstars. The fans would have loved to see such talented wrestlers brawl.

#2 Randy Orton
Randy Orton and Ambrose have fought each other a few times, both in singles and tag team matches, but they have never had a proper battle inside the ring. The Dude was frequently attacked by Orton, but other than a six-man tag team match at WrestleMania 29, the two have not even had a high-profile meeting.
The charisma which Ambrose exudes in the ring is unparalleled; add to that his stellar mic work, and he would have provided the perfect foil for The Viper. Fans would have loved to see them brawl. Given the fact that both of them are good at portraying heel characters, it would have been a fascinating rivalry.
