Universal Championship - Triple Threat Match
Participants: Brock Lesnar(c), Roman Reigns, Bobby Lashley

Please take the title away from Brock Lesnar. I don't even care who takes it away from the so-called 'Beast-Incarnate'. Sure, I will boo Reigns if he wins, but I will be glad that at least the Universal Championship will be defended on every PPV and will appear on every Monday Night Raw.
Although the match is not yet fixed, this seems like the logical decision. Reigns will face Lashley (sigh...once again) for a title shot at Summerslam. It does not seem likely that Lashley will defeat Roman two times in a row, so Lashley vs Lesnar is out of the window. Also, WWE will not trust Reigns and Lesnar again after their disappointing bouts earlier this year. So, Reigns vs Lesnar is out of the window (hopefully). The only option remaining is Reigns vs Lashley vs Lesnar.
The triple threat match is not unlikely either. A lot of #1 contender-ship matches have ended with a lack of conclusive decision thus, expect the same to happen this week on Monday Night Raw.
It seems like WWE is finally ready to strip Lesnar of the Universal Championship and hand it to Reigns. It is evident that Reigns will not get cheered no matter how long WWE waits, so it is best to give him the championship. He will not get cheered after his victory, but he will not get booed out of the building either.
But, I will go ahead and make a bold prediction: Strowman will cash-in his MITB contract. Thus,
Winner: Roman Reigns, but Strowman will cash-in his MITB contract.
Match predictions: Lesnar will get pinned by Reigns as it is unwise to take the momentum off Lashley.
