How do you catch rare / legendary pokemon

[Kirby]

And don't just say you use a masterball, do you clone masterballs, hack them, or just give up and are content with one ect.

I either:

1. clone masterballs from emerald to catch anything gen 3 or 4 easily

2. if I don't feel like cloning or in gen 5 I:

-buy a ton of timer or dusk balls, both are more effective than ultra balls in the right situation
-save in front of it
-paralyze the the pokemon
-get it to one pixel of health (fuck false swipe)
-spam balls until I catch it, die, run our of balls, or it struggles...
-repeat until caught

or use sleep. either works.

dont forget that crobat is how you catch entei, and masterball for raioku!
