The SubRoost set is actually most dangerous, at least now that ChoicedRaptors are running around, most people doesn't see it coming until something has died
I actually have a little fear to let him put a sub, that's why my NP celeby stayed in staraptor, they speed tie so I risked getting outspeeded (and lost) and he used sub, then i used Psyquic again and he died, this is in no way a reliable way to kill staraptor (and i only new he was SubRoost after loosing Dusclops, this is one of the reasons he is so dangerous, he speed ties with the 100 pokes (the most important tier in UU with the pixies and many others) with reckless his BB is great to just destroy, and CC for the few things that actually resist it, not a lot can swich into SubRoost without loosing all of his health when forcing him out (and even if he has lost 75% of his health, he can Roost and swich, getting to 50% or more
