Here is a few things You only need to breed ralts for mean look because ralts can't learn false swipe and it learn hypnosis at level 45, level 53 for kirlia
Breed a female ralts, kirlia, or gardevoir with a male Gastly, haunter, gengar, Misdreavus, Duskull, dusclops, dusknoir, yamask, or cofagrigus with mean look to get ralts with mean look.
Breeding a male ralts is a 50/50 shot for male or female so it could happen on the first set of eggs.
For hypnosis I would train ralts to level 45 holding the everstone to have it learn hypnosis then evolve it into kirlia then gallade.
Gallade learns false swipe as a TM move so there you go.
Hope I helped
