#6. Gauntlet Match for the Tuwaiq Trophy

Admittedly, the Tuwaiq Trophy isn't the most exciting prize one can imagine. Either way, it's a fairly star-studded line-up, with United States Champion Andrade returning from a one-month suspension, AJ Styles making his in-ring return after a month, and Rey Mysterio returning after being attacked multiple times post-Royal Rumble 2020.
We anticipate that The Undertaker could make his big return and confront AJ Styles, possibly setting up a match at WrestleMania 36. As for who will win, it's an interesting pick between Andrade, Bobby Lashley, and Rey Mysterio.
#5. The New Day (c) vs John Morrison & The Miz - SmackDown Tag team Championship

The Miz and John Morrison have gained momentum since the latter's return to WWE. They've picked up a feud with The New Day and Morrison has defeated both Kofi Kingston and Big E.
While it hasn't been a heavily-featured match-up, this one could be a show-stealer. A title change is within the realm of possibility.
