That means absolutely nothing. Mard was an ass who thought he was better than everyone like villains so often do. And just because he said something, doesn't make it law. Hades said that Meredy was stronger than Erza and Juvia together, but we both know that wasn't true. And you keep giving these power level estimations as fact and using them as justifications, but, as you say, they're your opinions, not fact.

If she can manage to find and attack someone with no senses whatsoever while she's in pain so crippling that even a gust of wind causes unimaginable pain (all of this after being tortured), then I think it's clear who the victor would be assuming the plot demanded it. You are severely overestimating the logic Mashima puts in Erza's fights. :P

Once again, you are forgetting that Minerva's opponent was Erza in her infamous flame pants no less (translation: logic doesn't apply). And Minerva's Magic revolves around the manipulation of space. I just don't see someone who's abilities revolve solely around brute force countering her Magic.
