Caught Tornadus w/ a quick ball (after catching a Golbat w/Mean Look and bringing its health down to red), caught Cobalion, Terrakion, Virizion, and Volcarona w/ Ultra Balls and Quick Balls, used the Masetr Ball on Kyurem. However, in Volt White I still have my master ball. Caught Kyurem with an Ultra Ball.
I MIGHT use it on Metang in VW weird as that sounds. Metang have a horrible catch rate and I remember wasting a lot of time and ultra balls trying to get it in normal Black version. I still don't have one actually. I ended up killing it by accident.
