So I'm breeding my first team in X and Y, and I'm trying to get a Deino with perfect IV's. My only ditto is one with 6 perfect IV's, and it holds Destiny Knot, which transfers 5 IV's. However, none of the Deinos I have gotten so far has even 1 perfect IV! I checked, the little perfect IV markers are there. I know the ditto has perfect IV's also. I'm just straight breeding those two until I get one with perfect IV's in HP, Def, SAk, SDf, and Spd. What am I missing here?
