Koga is the Poison-type Gym Leader. His team consists of two Level 37 Koffing, a Level 39 Weezing, and a Level 43 Muk. All are weak to Psychic and Ground-type moves. A strong Psychic-type Pokémon like Kadabra/Alakazam or Hypno will be incredibly effective. Ground-types like Dugtrio or Sandslash are also good choices. Be aware of their Toxic and Sludge Bomb attacks, which can inflict heavy poison. Bring Antidotes or Full Heals. Focus on one-shotting them if possible.
