Have a Fast Ball with you. This ball should catch at first time. If not, stack up on Ultras.
The master ball but i would suggest not using it on zapdos.
Ultra Ball
When catching Celebi, you should have a cherish ball. Throw it and it will be an instant catch. (DO NOT USE A MASTER BALL OR ANY OTHER BALL.)

Ultra ball :] the thing i do is, fist when you see Zapdos, save the game. so, if you don't catch it, you can just turn the power off and try again. but, catching the legendary Pokemon takes foreva, but you have to be patient. hope this helped :]

I would use a master ball.
You can catch any pokemon with any ball, you just have to be lucky. I recently caught a Zapdos with a regular Pokeball.Fastballs are a good ball to use at the start so they're probably your best chance at catching the legendary dogs without a pokemon with Mean Look/Arena Trap/etc.
any ball that you have the better the ball better the chances of catching it

He's in front of the power plant dealio. You have to have all 16 gym badges, fast ball's are the best to use. If that doesn't work, use Ultra balls until you catch him.
As you may know, Masterball is the best ball. I have both yellow, silver and gold. After I got the Masterball in either silver or gold, I traded with yellow. By making a pokemon hold the Masterball you trade it and in yellow you can clone it to have more of the best ball in the world. I would guess that Masterball is a lot easier to use when catching Mewtwo that a pokeball.
A master or ultra ball is good.
