Toph vs Edward Elric I'm curious as to how this would go down under a handful of situations.

Let's have them fight in two different locals, one a large mostly empty field, and the other a city with lots of materials that could be used for metal bending or alchemy.

I would also like to consider how well Ed would do with normal automail vs platinum automail.  Does he even stand a chance with his normal prosthesis if Toph doesn't enter the battle knowing he has them?  How quickly could she figure that out?
