[REQUEST] IV Breeding advice

[rosez12]

in order to breed with 2 sandshrews you need to update your parents every time you get a sandshrew with better iv. thats why its much easier to use a ditto. once you get a female one with 4 iv you need to update your parents. same with the male. 4 4 then 5 4 and 5 5 and so on. if you stick to the same 3 iv parents all the time you will never get a perfect one.
