I keep sane when breeding my making it more involved, and a challenge.
For example, if I wanted to get a 5iv Relaxed Aron, I'd breed any random Aron I had, giving it the Destiny Knot to hold, and giving a Power item to the 6iv Japanese Ditto I permanently keep in the Day-Care. Then, I keep breeding until I have a Relaxed Aron, which will have at least 3ivs.
Then, I give it the Everstone, the Ditto a Destiny Knot, and keep breeding. When I eventually obtain a 4iv Aron (which doesn't take that long), I substitute it for the 3iv Aron, and continue breeding. With this method, it doesn't take too long to get a 5iv Pokemon.
The other advantaged with this is that because the Ditto is Japanese, I can breed for a shiny and a 5iv Pokemon at the same time. This saves a lot of time.
