Gastly with Hypnosis?

Ok, I caught a Gastly on diamond, took it to the move tutor so it had hypnosis then traded it onto white and bred it so I was its OT. I have now restarted the game but still have the bred gastly. However I was stupid enough to leave it in the day care for too long and it has now forgotten hypnosis and I have no way of rtading another one over from diamond until I've finished the game (I'm now level 10s), anyone want to trade me a a pair of gastly (different genders) both with hypnosis or a gastly with hypnosis and a ditto? please! gengar is probably my favourite pokemon and it isn't half as good without hypnosis, thank you!!
