btw I was breeding corphish and I've come up with three different natures, all equally good; naive(ice beam in particular, possibly hp elec I have to check IVs), adamant, and now jolly. I think I've finished adamant/naive, but I'm still breeding jolly in SS.
jolly/naive allow it to outspeed elekid/voltorb/diglett, while adamant ties with gligar and the 19 crew (but notably outspeeds non-scarf gastly)
since you were the one to give me the main parent, which nature should I do first?
Most likely I'll do all of them, but since you get the free copy I think you can decide which one you want :)
