Thank you for your time and help !
I feel that I understood you, Let me give you example about Sandshrew (ground one)
- First I need to catch female Sandshrew with one or more perfect IV (Lets say speed IV), then I need any common male rattata. (question about this step: correct me if I am wrong if I catch female Sandshrew with no any perfect IV and with male rattata can I actully get hatched egg with at least one perfect IV Sandshrew? I feel this way is faster than trying to catch wild Sandshrew cos I can have like 5 eggs on the same time so i have faster chance to get at lease 1 perfect IV).
- Now I give Power anklet to Sandshrew, and bring ratatta and Sandshrew to the day care, I get eggs> hatch them> I should now get 100% Sandshrew with perfect speed IV, And by random maybe I get any other perfect IV (let's say attack), I should again give this new female Sandshrew power bracket so I Get in the new pokemon max speed and attack IV, And so on until I get 3 perfect IVS.
- I should now give the new female Sandshrew with the 3 perfect IVS (31 max) destiny knot, and breed her again so maybe the IV may jumps from 3 perfect IVS to 5 or 6 perfect IVS (31 max).
- About the Macargo the nature changer should be easy.
Is the example above correct ?
