How do i catch articuno on without using a masterball and why do i keep missing with any other ball???

Question

I was playing pokemon yellow and I tried to catch articuno. I found him and everything was fine. However, when i threw an ultra or great ball at it, it said that i missed!! I am wondering if i have to have a certain type of ball to catch him, like a master ball, and if so, how do i get another one when i believe i used it on moltres??????? can anyone help me????

Answer 1

make him sleep and battle him so he is weak but don't faint him or else you cant battle him again use ultra balls buy a lot...you were suposed to use the master ball for mewtwo  

Answer 2

well save it before you fight him and take a fewlow leveled pokemon to hit him but not too hard so his healthis very low, use the strong pokemon to get his hp low then the weaker ones to lower it to almost none and then use the ultra ball and idk if it was ever proven to work or not but hold the b button i gues its a rumor that it helpsidk good luck

Answer 3

put him to sleep and weeken him but make sure you save before batling him
