the ultra ball is what i used to catch it...but you could use the master ball after you get it
master. no other ball can hold it.
Yes, the Ultra Ball has a 4x catch rate than a Premier Ball, which has the same catch rate as a normal Poke Ball. It is commonly used to catch rare or Legendary Pokemon.
If you are in battle with another trainer you cannot catch that Pokemon that belongs to them. But if you find out where that Pokemon's habitat is (by using the pokedex) then you can go and catch it with a poke ball, great ball, ultra ball etc...

Apricorn have nothing to do with capturing celebi. They are used to receive special poke balls from kurt.
