Ok I found the easiest way to do this Get 2 Magikarps (M) and (F) With different IV Spreads (Why we get two magikarps is because they hatch really fast its about 500-600 steps if you have a pokemon with Flamebody. Making this method a whole lot faster) Take them to the Battle Tower Thing In Lumiouse and enter in a single battle format. (Check them one at a time because you cant enter the same poke twice) Check the Male right down his stats by looking at the summary while in battle in the battle tower. Once you have written them down (Very important that you wright down their stats) Soft reset (L+R+Sel/Start) Now Put In the Other Parent and Right down his/her Stats. Once again do it while in battle in the battle tower in Lumiose now that you have checked both stats and written them both down soft reset your game. Now lets say the male had these stats HP 121, Atk 40, Def 56, SpA 39, SpD 89, Spe 63 and the Female had these stat summary HP 140, Atk 43, Def 32, SpA 54, SpD 72, Spe 45 Put them in the daycare (Make sure one holds a Destiny Knot) The very first egg that they make you want to REJECT it. As soon as you have rejected it SAVE your GAME! Soft reset and ride around until a new egg is ready get this egg hatch it check its stats exactly how we checked for the parents. lets say you want a 5iv pokemon Goomey like me with 31/x/31/31/31//31 (If you dont understand this code its simple It Goes HP,Atk,Def,SpA,SpD,Spe all its saying is I want a Goomey with 5ivs but I dont care for the Atk stat this being the "x") and You have a two Goomey Parents with Dad 31/31/31/x/x/x and Mom x/x/x/31/31/31 ok you will need a magikarp with Hp, Def, From the Father Magikarp and SpA, SpD, Spe From the Mother So you want a magikarp with HP 140, Def 56, SpA 54, SpD 72, Spe 45 Once again check the baby's stats in the battle tower in Lumiose Once you get that spread soft reset your game take both Magikarps out from the day care and put in the two goomey parents with these stats Dad 31/31/31/x/x/x and Mom x/x/x/31/31/31 The egg that they make will be a perfect 5iv Goomey because the game already determined what stats it will pass down from the father and mother and your done. Now lets say you didn't get the correct spread in the magikarp baby an Example of this would be HP 143, Def 56, SpA 54, SpD 89, Spe 63 (Keep in mind we aren't checking the Atk stat because we dont care for it on goomey) The HP of this baby magikarp is a Wild Card because neither parents have that stat The Baby got Def, SpD, and Spe from the Father and SpA, from the mother since this is not what you want soft reset ride around till an egg pops up deny it save soft reset ride around till another egg appears take this egg hatch it check the stats. Rinse and Repeat until you get the desired stats that you want passed down from father and mother. Once they have passed down the desired stats soft reset your game take both magikarps out of the day care put in the parents of pokemon you want perfect Goomeyin this case and have one parent hold the Destiny Knot the baby should now be a perfect 5iv (Assuming you got the desired stats passed down from father and mother magikrap reset your game and took em out and put the goomey parents in)
