Edgeworth is properly placed, but I would argue Phoenix should be in the top left corner.

He has regular encounters with the supernatural, and his specialty is bullshitting his way to what must be true regardless of how outlandish it sounds.

Though, I guess it depends on what qualifies as "intuiting the mechanics of the death note." Phoenix will definitely stumble his way into something close to the truth even if by accident, but whether he actually believes what he's saying is true because he arrived at the conclusion logically or if he believes it's true because he believes so deeply in the innocence of his client that the supernatural explanation must be true is up in the air.

If "using the wrong equation to get the right answer" doesn't count as intuiting the mechanics of the death note, then I could see the argument for putting Phoenix in the bottom left. But he would absolutely stumble into accidentally describing how the Death Note works, and confidently use it in his defense because you can't prove that it's not true, even if he doesn't fully understand why what he's saying is true.
