>>26869192I'm not sure how much you already know or how far you are into your breeding but the basics are that Hidden Power Fire is odd IVs in HP/Def/SpDef and even IVs in Atk/SpA/Speed, so ideally you'd want 31/30/31/30/31/30
Basically this means the only IVs you want to be perfect are HP, Defense, and Special Defense, while the others need to be even numbers (i.e. not 31): ideally you'd want 30, but it can be 28, 26, etc. if you don't care about perfection, and attack doesn't really matter in this case so it can be low (but still even!)
What I did, starting at the very beginning, was breed a Magnemite with perfect HP/Def/SpDef, used that one to breed more perfect HP/Def/SpDef ones, then checked the exact values of the other unknown IVs until I found some that had good, even values
So my Magnemite parents went down the line like this, trying to get ODD/EVEN/ODD/EVEN/ODD/EVEN:
>31/??/31/??/31/??>31/25/31/28/31/29>31/10/31/28/31/29>31/10/31/28/31/28With the last one having HP fire
Hopefully that helps, though whether is does or doesn't I wish you good luck
