4th Gen Master Ball: When do you use it?

[Porygon Z]

As the title says, I'm asking you on which Pokèmon do you use your Master Ball.
I used for Entei, it was the last Legendary Pokèmon that I miss, so I decided to use it on him!

 

[Yes nah Chansey]

When someone offers you a Mew on the trading forums ;)
