Night Slash?

[PKDante]

Hi, this is probably a stupid question but how do I teach a Ralts / Gallade night slash?

Do I have to breed it?

Any help would be much appreciated!

DAN!

Its a Heart Scale Move Tutor move thingy.

Thanks :)

I knew it wasn't a TM or an egg move!

Trust me to forget the move tutor!

Thanks again!
