You get a masterball from prof. Elm after beating the johto league. In the case of catching suicune, i wouldnt use a masterball. theres only one unless you clone them so save it for cloning or Lugia or Mewtwo. When i caught suicune, i brought its HP right down then used around 20 Ultra balls until i finally caught him. Have fun hope this helped.
