Why would you match Elfman against Jackal?

Elfman is a pure close-combat fighter who can't eat flames. Everytime he punches Jackal (if he can get close enough and manages to connect a hit in the first place - remember the couldn't even touche Bacchus), Jackal would put a curse on his arm and blow that up.

Unless Elfman somehow miraculously dodges into close-combat range and on-hit-KOs Jackal, he's toast.

And I think Juvia would take her match quite easily too. Even if Arana's webs even affect Juvia's body at all, I really can't see Juvia even having to try hard. Arana was one-shotted by Ren in the GMG after all.
