To obtain Cobalion you have to go to Mistralton cave. There you have to use flash to illuminate the cave search the cave for a flight of stairs and then another. You will reach the guidance chamber where you have to talk to an old man and then search the chamber you'll find Cobalion at level 42.
colbalion,terrakion,virizion,kyurem,tornadus,thundurus,reshiram,zekrom,volcarona landorus,
you must first go to the cave were you have to use flash and get Colbalion and then you have to go to the Rumination field (the old man blocked it before, but after you get Colbalion he moves and the stones go away too) and Virizion is waiting for you.
I beileve that if it is like most other legendaries, you only have ONE (1) chance to catch it, If you killed it, too bad. Try trading for it.
Victini, Zekrom, Reshiram, Tornadus, Thundrus, Landross, Kuryuum, Virizion, Terrakion, Colbalion, Keldeo, Meoletta, and Genesect. (Meloetta, Victini, Keldeo, and Genesect cannot be obtained through normal gameplay.)

It can not be in Pokemon black but you can get it in Pokemon white.
There is no Contest Hall in Pokemon Black because Pokemon Black does not have Pokemon Contests. Instead of Pokemon Contests, Pokemon Black has Pokemon Musicals. Pokemon Musicals are held in the Pokemon Musical Building in Nimbasa City.

Pokemon black by far. but if you have a choice between Pokemon black or Pokemon white get white. you can get more Pokemon in white than black , plus there is white forest and you can get rare Pokemon there i think
