I would, but I'm trying to complete Leaf Green with a Bug team XD.
Have you done a Synchronized ditto chain yet?
If you don't know what one is, get a Synchronizer of the nature you want (Naive for you), let it faint in the patch of dittos (you may need about 170 masterballs for this), then chain enough ditto (170) and 85 should be Naive natured. Then out of those 85, check all the IVs and between them all you should have the IVs you want, so it makes it easier to get better offspring.
