The main fight always be (even in our real world): Outlaw VS a Defender of the law, which in world of one piece means Pirates & Revolutionaries VS Marines & World Government & who works for them, then [Yonko & Supernova & other pirates & Revolutionaries VS Marines &  World Government & Shichibukai] (as they works for the  Government  and  defence the law, once they quit they become a pirate on the other hand of the fight).

But even that, the side fo the owtlaws a fights with in it (like Yonko vs Supernova) and it changes depending on the persons and how the story goes so it is hard to say who is vs who, but the other side don't have a fights with in it.

If you looked at every battle in the series you will find that it is an Outlaw vs a Defender of law or Outlaw vs Outlaw (except a few times like Doffy vs Moriah and Kuzan vs Sakazuki).

This idea could help you :)
