Pokémon X and Y Playthrough Discussion

Breed two with 5 perfect, them each having the one the other doesn't, then destiny knot those two together till you get the right nature on a perfect little baby.

You should start out everstoning/egg moves then focus on IV breeding, but you're going to have problem with the IV's. But to be honest, it's rare you'll be dealing with a mix attacker. Aegislash is fortunate because you only need HP/ATT/Def/Spdef

Speed and sp.att is worthless.
