>make sure you don't KO itFalse swipe or super fang

>using status alimentsOne nondamaging move. Sucks if the legendary is immune to paralysis or has a way to heal status
>using the correct ballDusk or timer ball
>make sure it doesn't KO you before you catch itUse healing items
So if by 'skill' you mean something you could do with 3 separate pokemon (or less) and buying balls and potions. I've often even gotten all 3 necessary moves on one pokemon without much effort.
