At this year's Survivor Series, The Vision is set to battle Team CM Punk in the WarGames Match. Paul Heyman has ensured that he has some of the biggest superstars on his team. Logan Paul was the first to align himself with the villainous faction, followed by Drew McIntyre, who was brought back from a suspension by The Oracle.The heel team was completed on this week's RAW with the return of Brock Lesnar. That said, while Team CM Punk looks equally formidable on paper, if not more, the massive egos of its members may ultimately be the reason for its downfall at Survivor Series: WarGames.In a shocking possibility, Roman Reigns could turn his back on his teammates and join The Vision at the upcoming PLE. The OTC also returned on RAW, neutralizing Brock Lesnar and seemingly joining the babyface team for WarGames. However, while a common enemy may have brought them together for now, Reigns is far from being on good terms with any member of Team CM Punk, including his cousins.The two-time Universal Champion doesn't trust The Second City Saint and has advised his family not to do so either. Despite that, The Usos have come to Punk's aid when the latter needed manpower. Moreover, Jimmy and Jey inadvertently cost Reigns his match against Bronson Reed at Crown Jewel, something the OTC may not have forgotten.As for Cody Rhodes, he was the one who ended Reigns' historic 1,316-day reign as WWE Universal Champion. While they have previously worked together, the bad blood is likely still there. Team CM Punk consists of some of the biggest names in the company, but one crucial thing it lacks is cohesion.Roman Reigns may show his true colors and revert to a villain by betraying his team inside WarGames, helping The Vision to secure the win. The OTC may pick Paul Heyman's side over his family and join The Vision. That said, this is only speculation, and nothing has been confirmed.The Vision ousted its previous leader, Seth Rollins, last monthAfter his hard-earned victory over Cody Rhodes at Crown Jewel last month, Seth Rollins was in a mood to celebrate on the following RAW. However, he was met with a betrayal from his own stablemates, who kicked him out of the faction.Bron Breakker seems to have assumed the leadership role at the moment, but with the addition of Brock Lesnar to the team, there could be a power struggle between The Beast Incarnate and The Dog of WWE if Lesnar decides to stay in The Vision after Survivor Series.The Men's WarGames Match has an interesting lineup this year. It remains to be seen how it plays out on November 29.
