The fact that Ultear was able to negate Gray's attacks doesn't automatically means she can negate every attack that comes her way.

First of all, she has to put enough Magic behind her attacks to negate Jura's rocks. If Jura wastes 1000 MP (for example) on a Rock Pillar and Ultear tries to negate it using only 500 MP (for example), she'd just get Jura'd.

Second of all, she has to react to the opponent's attacks. Ultear has no chance of negating Jura's Magic (assuming she can actually do it) since Jura was able to hit Laxus and Jellal with his rocks. And both of them have/had much faster reflexes than Ultear has/had. So she'd still get Jura'd

Third of all, Gray was able to hurt (and blitz) Ultear with his attacks pretty good. Jura is obviously A LOT more lethal (and faster) than Gray. She gets Jura'd pretty hard.

Fourth of all, she's a granny now. So she definitely shouldn't be on the list. (would still get Jura'd)
