I don't have any time to dissect these new developments, except for the obvious fact that Hoopa's ability is freaking terrible, and how both of them have so many wasted points in physical attack (seriously, they should've been swapped with speed), so I'll get back to you later on that. The important thing is that they're there.
As for the signature moves, Hyperspace Hole has 80 power, perfect accuracy (as in, like Swift), and hits through Protect and Detect. Do you run that, or do you go with Psychic or Psyshock instead? As for Steam Eruption, it's basically a 110-power, 95-accuracy version of Scald. Not exactly unexpected.
It should be mentioned, however, that by the time they're distributed, we're probably going to have access to move tutors at that point, so let's not panic over disappointing movepools just yet. Aside from dual physical STAB on Volcanion being impossible, I mean. No Waterfall and utter lack of tail nailed that particular coffin.
