Just tested this against two female trainers.Giratina-O: Is it still immune to having its Griseous Orb removed in some way, either by Trick, Knock Off, or Thief?
Acupressure: Does it now work through Substitutes?
I used Trick against Giratina-O and it failed, the same goes for Thief and Knock off
Tested accupressure and it indeed works behind a subtitude
I'll be testing Assist power soon, but it will take a while probably
