I have a 6iv male gardevoir can I breed it with a female chanderlure?
What one should hold the everstone?
What one should hold the destiny knot?
Will it work?
Give the Everstone to whichever parent has the nature you want your Litwick to have. Give the Destiny Knot to the other one, as it does not matter who holds the Destiny Knot because it takes IVs from both parents.
Hope this helps :D
