First i'd get it down to red hp, or low yello hp, then just throw ultra balls at it. throw about 5, then throw 5 timer balls then keep doing this process until you caught it.
if you have AR (action replay) then just use one of your 900 Master balls
MasterBall
Legendary Bird. Lucky catch. Try sleep
when you find that Pokemon if you have a master ball with you use a pokeball and you will capture it
u fart on the great ball and it gets magical powers. this also works if you fart on a pokeball.
go to seafoam island search for articuno wich is hard to find articuno so good luck

Ultraball, Duskball, and Masterball are your best choices. But sometimes, if the HP is low enough, it can be caught with a simple Pokeball even.
no you should not.
Solosis is exclusive to White.
yo face
to catch articuno easily you can weaken it and use a better version of pokeball like greatball,ultraball you buy them from the Pokemon market or find it master ball catches it no matter what but you can not buy that you can only find one or a go to saffron city and go to silph.co and save the old man on floor 11
Yes but it might take a while. yes, but it takes about 10min. or 30 at max its better to damage it then use it(or sleep it or paraylze).
