Catching Rayquaza, Groudon, and Kyogre

[Pokemon Trainer1]

Does anyone have advice on how to catch all three of the legendaries in pokemon emerald? I don't really have a set team, and I don't usually use the format for the competitetive battling stuff, so I'll just list all of my pokemon, their levels, their natures, their stats, and their moves (I don't do EV spread as I don't know how to calculate that.)
You may just tell me to train one of my pokemon to a certain level if you must. I'm currently standing right in front of Rayquaza after three failed attempts. The first six pokemon in my list are the ones that I have with me. I would prefer if you guys could work up a strategy for me with the pokemon that I currently have so that I don't have to go back through the Sky Pillar.


Pokeballs:
Pokeball x 25
Premier Ball x 1
Great Ball x 19
Nest Ball x2
Ultra Ball x6
Master Ball x1

The strategy that I have right now is to lower Rayquaza's defense with screech, while he's asleep (he always uses rest on the first turn) and then proceed to use false swipe. Then he OHKOs me with Outrage. after that, I can' get him because he's too fast. Oddish helps with Sleep Powder, and if he gets hit, then I use Moonlight.

You should ask about this in the Q and A thread. Don't post that wall of text though 0.o

Sleep it. Throw Ultra Balls.

There isn't anything else to it.
You don't need stats, etc for catching Pokemon, and it takes little to no effort to catch them when their HP is low enough.

ANY questions go in the Q&A thread. This is a question.

 

[Riddle]

Oh right. Q and A. Lol ignore me

 

[Wave⁂]

1. Get all your Pokémon to level 55, at the very least.
2. Buy at the very least 50 Ultra Balls
3. Paralyze with Thunder Wave
4. Switch in your level 60 Aggron
5. Attack and chuck Balls until it runs out of Rest PP
6. Switch in Sceptile, get him to 1 HP
7. Chuck more Ultra Balls

REMEMBER ONE THING

VERY IMPORTANT

HOLD DOWN B WHEN YOU THROW THE ULTRA BALLS

Have some Timer Balls also. After 25 rounds I think it is about 4x catch rate, but I have been wrong before
