It looks like we have a couple of random new sucky abilities to go along with Truant. Except these Pokemon don't need to be nerfed. Like Murkrow, Absol, and Donkarasu taking critical hits more often or Mimilop not being able to use hold items or Delcatty's attacks all being normal. Nothing really useful, all negative. Very odd.
Still, Auto-Explode is just awesome and one more reason to love Skutank. Anyone knocking him out with a Physical Attack is going to get hit with an automatic Explosion attack. That's just freaking awesome.
Dosydon and Camerupt now have an answer to the super-duper weaknesses to water that everyone neglects to use them for.
The pine-tree's awesome auto-hail is pretty sweet.
