Re: Best way to catch Rayquaza w/o masterball in emerald
I only Masterball Mewtwo. I keep it in bag when in Hoenn.
All others get blasted by Swellow's Endeavor after fighting a bunch of Carvanha/Sharpedo to get Swellow in the red. I usually lead with Raichu's Thunder Wave for those not Groudon. For Groudon, I usually lead with and put it to sleep with a Yawn from Slaking.
Magneton is my second for Rayquaza after Swellow has Endeavored. Magneton uses Thunder Wave. And if Rayquaza used Fly, then I use TWave again.
-Net Ball for Kyogre
-Ultras on all others
