#8 The Bludgeon Brothers (Harper & Rowan)
The Bludgeon Brothers started off the year as a dominant force to be reckoned with as they defeated the likes of Breezango and the Ascension. They then interrupted a SmackDown Tag Team Title between the New Day and the Usos at Fastlane before winning the SmackDown Tag Team Championships from the Usos in a triple threat tag team match that also involved the New Day at WrestleMania 34.
The Bludgeon Brothers then successfully retained the SmackDown Tag Team Championships against the Usos in their mandatory rematch at the Greatest Royal Rumble. They then successfully defended the SmackDown Tag Team Titles against Gallows & Anderson at Money in the Bank and on an episode of SmackDown Live before entering a feud with Team Hell No.

Team Hell No faced off with the Bludgeon Brothers in a match where the Bludgeon Brothers scored the biggest victory of their careers when Harper pinned Daniel Bryan. The New Day then defeated the Bludgeon Brothers by disqualification at Summerslam before the New Day won the SmackDown Tag Team Championships from them on the SmackDown Live after SummerSlam. The Bludgeon Brothers have not been seen since then because both men are recovering from injuries.
