For example. You and I would be a team and Rill and Skall would be a time. We'd all be at the same location, fighting. So you could, potentially, set up devastating attacks based off each other or try and gang-beat one person down real quick. 

If that's to complicated than think of it as an old school WCW tag-team fight, with only person fighting at a time per team and then having to tag the other in. Potentially allowing for a sweet team attack for one exchange. Ya know, you put Rilla's face on a steel chair and then I do a leg drop on it from the top turn buckle!
