catch a sneasel,it may cut your health in half,but it doubles your line length,thats what i did so i know it works.hope i helped!

There is the dark type way, but as the other person said, it cuts down on your health. You can also use the Ice type to freeze him in place. That is how I did it.

when you use ice type pokemon it doesn't work it rescued itsself at once. teddiursa's trick ist better

its easy when it goes round in circles theres your chance watch you dont hit it whatever you do

use sneasel so i did it

All I did was wait until he went in circles then my Minun had full lightning so I blasted him and caught him. Good Luck!!!!!!!!!!!!!!

you fart

find a pokemon with 3water then when steelix is going in a circle put it in a bubble then hit him with a thunder and steelix is gone

u get a medicham and ur minun/plusle use plusle/minun on the steelix when it in circles
and then use medicham then u capture it easy :)!!
