With that then, I think I'll have to go Phoenix. I imagine theirs more feats probably, but looking towards Battlers intelligence stuff, while impressive, it doesn't seem as impressive as some of the things Phoenix has done. Phoenix creativity and on the spot thinking, bluffs, and extreme skill at flipping the picture to see it a different strange but accurate way can really help him. With his typical time to get evidence as well helps seal in it. Even on the spot Phoenix has pulled off some good feats. Like in the circus case, someone starts giving him a BS story that he saw his client kill the victim. And he calls it out right then and there and didn't even have evidence on him. Then the time he had amnesia and did know what the case was, who his client was, or anything in general. Even forgetting how to Lawyer. Yet he picked that all up in a matter of minutes and won the case. And this also had a handicap because his client had a supernatural bad luck charm to them. Which was very consistent. But despite being almost as crippled as you can get, Corrupted prosecutor, No idea about the case, no memory of anything, and evidence that made the case seem almost straight forward she was the killer, plus the bad luck charm. Still works through it. So yea. I think I'll go Phoenix. On the spot brilliant thinking and skills to put things together, bluffs, general luck/Skill, determination, and with time to gather evidence and make his case even stronger. Blue Bird FTW
Now I haven't seen this other guy. I'm going off what I can see and what little I know of him. I of course know far more on Phoenix. So don't hate me if I'm missing stuff.
