What do I use...
Well, when I finished Red, this was my team:
- Level 55 - Used against Grass, Ice, and Bug types
- Level 53 - Used against Poison and Psychic types
- Level 53 - Used against Water and Flying types
- Level 54 - Used against Fire, Electric, and Rock types
- Level 56 - Used against Fighting and Ghost
- Level 53 - Used against Ground and Dragon
I believe they were effective against every type of Pokémon I could have encountered. Of course, I had to know what type the Pokémon was, though. Which I sometimes did not.
