For the Latis, you need luck to encounter them. Once you do, then you can track them with your Pokedex. Use a Wobbuffet with good Sp. Def. It's ability will prevent them from fleeing, and you don't want Mirror Coat to be too powerful, so it has to do less damage, hence the sp. def
There's no way to encounter Deoxys other than by event, and I'm sorry to say that all the events are over.
For the Regis, I'd bring something to put them to sleep, and LOTS of ultra & Timer balls. You'll need them.
Don't expect to see me around anymore, except in the Brawl threads
Yes...and you can only get the Aurora Ticket from a special event.
Switch the master ball to your 6th slot, fly to Veridian and watch the old man catch Weedle
Why is it the stuff I find hard to do everyone else finds esy and vice versa?
Paralyze any and all legendaries and use approx. 832748953784395724 Ultra Balls. I've never caught the Latis (yet) but I caught the Regis, Mewtwo and company pretty easily through paralysis.

Hey, if you got FRLG, then you could train a ariados with spider web. I am sure that would be less risky than a wobbuffet. I mean they do learn night shade and all. Also, you could breed for signal beam and get a super effective attack.
But I guess the speed thing would be a problem. Still, for me wobbs always seemed a bit dangerous on legendaries.
And as I sit and talk to you,
I see your face grow white.
The shadow hanging over me is no trick of the light.
The specter on my back will soon be free.
The dead have come to claim a debt from thee.
How can one person be so endlessly disappointing?
Hey, does anyone want to trade and Battle and stuff with me when Diamond and Pearl come out in America? It's really taking a loooong time.....
