Where do you get quick balls in Pokemon black?

You can't get Quick Balls in Pokemon Black. They were introduced in Pokemon X and Y.

In Pokemon Black, you'll have to rely on other Poke Balls like:

* Poke Balls: The most common and basic type of Poke Ball.

* Great Balls: Slightly better capture rate than Poke Balls.

* Ultra Balls: Higher capture rate than Great Balls, especially effective against rare Pokemon.

* Safari Balls: Can only be used in the Safari Zone and have a good capture rate.

* Master Balls: Guaranteed to capture any Pokemon, but you only get one.

Remember, using the right ball for the situation can greatly increase your chances of catching a Pokemon!
