>>19306957Fire/Water/Grass is a great Rock-Paper-Scissors introduction to type matchups. Anything else would be ridiculous to offer a new player.
What would you suggest? Fighting/Dark/Psychic right out of the bag? "Here, you're only 11, but please choose between this Pokemon that can read your thoughts, this one that is very clearly evil, and this one that could probably beat you up and take your lunch money."
Fuck that. Give me a grass-lizard.
