Ralts can be found near Petalburg City. It's pretty hard to get. You can get it easier if your pokemon like you. It may not seem good at first but it evolves into Kirlia then Gardevoir, probably the best non-legendary psychic pokemon.
Latios is a dragon and psychic type of Pokemon. In Pokemon Sapphire, you can find him roaming around in random locations.
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!

Use psychic, electric, or rock moves.
Psychic Pokemon, as well as in any other Pokemon game are weak to the types; Bug, Dark, and Ghost. However, Psychic has no effect at all on Dark Pokemon.
In Pokemon Sapphire, Ruby and Emerald the 7th Gym that's located in Mossdeep City has Psychic type Pokemon.

Jirachi is a legendary Steel and Psychic type Pokemon. It does not occur naturally in Pokemon Sapphire, and can only be obtained through official Nintendo events.
There is no Pokemon mansion in sapphire.
He is not in Pokemon: Sapphire. You will not be able to find him. He is in Pokemon: Diamond, Pokemon: Pearl, and Pokemon: Platinum. You will definitely have trouble finding him in Pokemon: Sapphire.
the best Pokemon to choose early inn the game are Abra and ralts.
Try to use a flying Pokemon or psychic Pokemon, I used Ralts and Taillow to beat him. Yeah so try using flying or psychic.
