5 Possible partners for Braun Strowman against The Shield 

#4 Dolph Ziggler and Drew McIntyre

Dolph Ziggler and Drew McIntyre will definitely be on call

Even if WWE wanted to lazily book this entire storyline, they already have a tag team that has an issue with Dean Ambrose and Seth Rollins, so why wouldn't Braun Strowman go ahead and ask Ziggler and McIntyre to join him?

The easiest way to book this would be for Strowman to decide to go it alone against Roman Reigns once again before Rollins and Ambrose descend and Ziggler and McIntyre then come out to aid him. This wouldn't be because of any kind of alliance between the three men, this would literally just be a case of common enemies.
