I think that all forms of deoxys bar defense should be banned as I can't really imagine how a broken lead that sets up so many hazards can be beaten with OU like stuff. The attack form, imo is just too powerful and can do to much damage.
With mew, its awesome support movepool is too great and under dual screens makes it just like how annoying it is in ubers. Also, donut, mew is used much more often as a SR lead in ubers, not a BP user.
However, with wobba, I really struggle to find why I wouldn't use shanderaa now so I think that it deserves to be retested. Also, you need to think about wynaut.
I'm also not convinced about darkrai as its stats are still quite low and we should test more of that before we are sure that it is uber.
