Its been a while, so I figured I'd post a new topic
New Topic: Have you ever caught a legendary Pokemon in a Poke Ball?
I wish I could say I have.
All I ever used were Master Ball for the Roamers (Mesprit, Raikou, Entei, Cresselia, etc)
Ultra Ball for the others that aren't in the caves
Desk Ball for the others in the Caves
Great Ball on Uxie!
