@Daywlaker- well, Naruto only gained his advanced natures at the very end and probably just didn't know any techniques for them. While I do see your point, I feel advanced natures are too useful for someone as old as Onoki to have never bothered to learn even the most basic applications (again, simply deflecting Sasuke's sword with magnet release wouldn't be all that hard).

@Iar Sensei- By 74 and 75, do you mean the anime or manga? Not to be "that guy" on the canonicity of events, but it does make a difference.

Edit- ok, I got it now. Well, at that point in the anime, the idea of kekkei tota didn't exist (maybe it did, but I don't think the anime writers knew what it was, really).

I think that the whole "one in one hand, one in the other" thing was more of a metaphor for the internal blending of two differently natured chakras. There's no set limit on how many natures one can blend in their bodies- people at the end do it with five.

Basically, what I'm saying is that I think there's more to it than a "neutral" element making it possible to mix two advanced natures. It's a combination of earth, wind and fire, not lava and magnet.
