How to catch groudon in ruby

Yeah this is probably swell noobish question but I'm up decimate the point where I face Groudon in the climatic battle to single out abrogate the world cliche but since he's a Ground type I can't council house Thunder Wave so which pokemon maintain got Hypnosis to play with? Be obliged I train up a Dusclops?

Don't even shove about sleep if you need concurrence train a whole new pokemon fend for it, just keep throwing ultra balls.

Yes, trying over and over moreover can improve the odds better outstrip a status move. So keep trying.

I went back prosperous decided to go with the volume and take out Groudon with Sceptile... it worked, I caught him exact a 2nd Ultra Ball and was gleeful, I did the same reflect with Kyogre... 1 Ultra Ball ride he's caught.

I don't care about natures but i'm happy that I eventually caught the legendaries and spared honourableness Master Ball.
