What pokeball should be used to catch moltres Articuno and Zapdos in platinum?

Use a master ball. Unlike Mesprit, they'll run away from you before you can use Mean Look. They also know Roost which heals their HP making them even harder to catch. To catch all three with a master ball get Diamond/Pearl. You also need another DS. Once you get the master ball from Cyrus in Diamond/Pearl have one of your Pokemon hold it in that game then trade that Pokemon, take the ball from it then trade it back if you want. If you saved the master ball in Platinum BOOM you already have two! After that delete your Diamond/Pearl game then do the same thing again. If you don't have another DS then use the master ball on the one you want the most and try to use quick balls on the other two.

actually mate if you use mean look it will work as long as the pokemons speeds high enough
