How can I catch Rayquaza on PokeMon Ruby Version?

You can do this, once he uses outrage twice sitch to swablu, if it says he got confused put him to sleep other wise swap out then swap to swablu if that one faints and put rayquaza to sleep. I eneded catching mine in a poke ball (No joke) on emerald with one poke left and that was the last pokeball. I didn't use masterball on anything, wnated to clone that lol.
