There are 3 types that work best against psychic Pokemon: Bug,Rock,Ghost, and Dark.
Psychic type Pokemon are weak to Dark, Bug and Ghost type moves. Psychic Pokemon can also struggle against Steel types as not all Psychic Pokemon can learn moves effective against them. Overall the best type to use against Psychic types is the Dark type. Since the Dark type is not only super effective against them but is also immune to Psychic moves.
Fighting-Type moves are weak against Poison-Types, Flying-Types, Psychic-Types, and Bug-Types. Fighting-Type Pokémon are weak against Flying-Types and Psychic-Types. My best guess would be leaf Pokemon but Ihavent played it in a while They are pretty effective against normal type Pokemon.
There are several types that work well against Rock-Types. Water and Grass are the most commonly used against them, but Fighting pokemon, Ice and Steel works as well.
If your talking about psychic pokemon, most get confusion and psychic (best in game) by leveling up to like second evolution. Psychic tms are pretty rare, but I always find a psychic somewhere during the game. Most psychic moves are best if your pokemon is good for them, in which you'll get them by training. Hope this helped!
Koga uses primarily Poison-type Pokemon. Psychic Pokemon would be the best bet. Ground-type Pokemon would also work, but will not be as effective against his Venomoth or Crobat.
