>>41853001>>41852378Yeah, psychic was supposed to also be weak to ghost, but a glitch made it immune instead. Combined with the fact that ghost and bug had no good moves and were largely secondary poison, it was more of a combination of factors that resulted in all the problems with psychic.
If you fix the glitch and add shadow ball and x-scissor, you could actually use Gengar, Pinsir, or Scyther to try and deal with psychic types. Alakazam would probably still be busted though.
