#2 Aiden English
Rusev Day was one of the most over acts in the tag division but never got the support from management. Later, Aiden English turned on Rusev and attacked him. He even cost Rusev the qualifying match for the World Cup tournament. Through their feud, the Nght in Milwaukee segment became a huge talking point but was abruptly ended.
For the last spot of men's Survivor Series team, Paige may organize a multi-man match which comprises both Rusev and Aiden English. Then Aiden can roll up Rusev for the win, much to the surprise of everyone, and thus continuing their feud.
The addition of Aiden could be a last-minute swerve. He could also serve as the participant who gets eliminated right off the bat. His elimination won't bother the team much and at the same time save other superstars from talking the pin early in the match.
