#4 Dolph Ziggler and Drew McIntyre
This is a coalition that certainly makes much sense. Drew McIntyre and Dolph Ziggler do not like Seth Rollins and Dean Ambrose at all. In fact, they've been embroiled in a feud in recent weeks too. Why would they not offer to join forces with the massive Monster Among Men?
It would lead to a classic case of McIntyre and Ziggler reuniting with a neutral party to take out some common foes. Bear in mind that they've had their run-ins with Roman Reigns in the past, and they are not very fond of him either. This is a match that is made in the deepest, darkest Hellish pits.
Plus, they are both fantastic workers and they can have some great matches with The Shield, when the time is right. It would also keep them in the mix and in the hunt for the Intercontinental Championship, perhaps for the time being.
