1. Wins. Grimoire Law at best will weaken the people who have more MP than the caster but will not oneshot KO them as it is supposed to. I think Erza's MP has surpassed that of Hades at this point.
2. Wins. He got damaged by Mard's thorns , he's a glass cannon.
3. If Memento Mori works on people stronger than the caster , then she stops here. Otherwise wins.
4. Wins.
5. Wins. Her magic was being negated by Marin.
6. Hard stop here. She can't hit him at all , combined with the bane particles and other deadly curses , she gets killed.
7. Wins. Gajeel had a high diff fight with LFD Natsu , which is a regular version of Natsu. Whereas Erza blocked partial END's blow. Even though END wasn't fully transformed , the partial version was still stronger than any other version of Natsu which he could access at whim.
8. Wins. Gray could go on par with partial END only after having the feelings of darkness powerup.
9. Loses.
10. Loses.
