I'm not saying the match was fair; it was clearly in Paul's favor as I'd hoped. I'm saying the match was relatively realistic. Very few things occurred that I wouldn't consider plausible. Almost every action had an easily ascertainable reason behind it.
There is no 'should have' when it comes to this anime. You can't say Gliscor 'should have' KO'd Torterra, because I can just as easily say Gliscor 'shouldn't have' done nearly so well considering their experience levels. DEM only refers to the impossible; i.e. Pikachu learning Feint during this bout. Evolution during combat is DEM, but this is an exception, 1) because it was expected, 2) because it ultimately accomplished nothing as far as the battle was concerned. Finally, it was good for the plot.
