Ah, ha! It should of been obvious, I knew the method. Just never thought about the name. Currently I'm breeding litwicks from jpn/usa regions. They are passing down IV 31 in sp. Atk, spd, and hopefully hp. I'm hoping for a shiny, then the issue becomes the nature. Which I could use the Everstone, but... I wouldn't get the two guranteed 31 IVs.
Best of luck on your shiny breeding.
