At the Royal Rumble, Christopher Daniels of SCU won the vacant WWE Intercontinental Championship. After defending it at Elimination Chamber and then the March 4, 2019 Raw Super Show, he was looking for contenders. At first, it appeared that he would be challenged by Nick Aldis. However, EC3 would also come out to challenge Daniels. Finally, Matt Taven of The Kingdom had been attacking Seth Rollins at different turns. He made an offer to Jason Michaels, saying that Michaels had a choice: Either add him to the Intercontinental title match at Wrestlemania or he would take out Seth Rollins, forcing Michaels to put him into the World title match. Daniels accepted the challenge from all three, despite the misgivings of his SCU faction mates, and Michaels made the match at Fatal Four Way.

Also at the Royal Rumble, Aero Star and Drago defeated The Usos in a ladder match for the vacant WWE Raw Tag Team Championship. At Elimination Chamber, they retained against SCU, and at the same event, War Machine defeated The Kingdom to become the Number One Contenders. Aero Star and Drago successfully retained their titles against War Machine at the March 4, 2019 Super Show. The following week, Aero Star and Drago defeated them again in a non-title rematch. After the match, The Kingdom came out and demanded a championship match. SCU also came out and wanted an opportunity. On the March 18 episode of Raw, SCU and The Kingdom had a match to determine the Number One Contender for Wrestlemania. The match went to a no contest when Aero Star and Drago, who were ringside, got involved after getting attacked by the Kingdom. As a result, Jason Michaels made the match a Triple Threat for the tag titles at Wrestlemania.
