You dont understand me man what I was saying is that if you have first hokage and Nagato fighting then you can not include the bijuu in the discussions because how can you have two of the same bijuu facing each other since currently 1-7 bijuus are currently sealed in the gedo mezo and hashirama tamed all of the bijuus. You see you can not have 1 tail vs 1tail because they both are the same, so all topics of hashirama vs Nagato should stop including the bijuus in the discussion. Now if they faced each other one on one then preta path will take care of hashirama wood realese.
