I just got a second Destiny Knot from a female trainer in Lumiose City and i was wondering if it stacks for the breeding process.
I mean, if i give a destiny knot to both parents, the baby will inherit 10 Iv or still 5? Do you think if that's the case, it would be a quicker process breeding two pokemon with good IVs and hoping for the right nature instead of using the Everstone?
