I currently have 2 Pupitars and I'm trying to breed a 5 or 6 IV Larvitar.

I'm not new to breeding but I've never done it for IVs before.

I currently have 1 female Pupitar, with 31 Atk IVs and 31 Sp. Def IVs and 1 male Pupitar with 31 Def IVs.

Could someone give me tips on how to go about breeding a Larvitar with 5 or 6 IVs. I can catch more Pupitars in friend safari if need be.
