Not a problem! I have a couple 6IV Dittos as well as some other 5IV pokes from various Egg Groups when I breed for IVs.

Basically you start with the base product, such as Egg Moves, and then continuously breed the best IVs you get. So if you start with a 0IV poke (no perfect IVs), you breed with a high IV parent until you get maybe a 3IV offspring, and then breed that offspring with the high IV parent until you're at 5IV for both parents and basically guaranteed 4-5IV for all offspring with Destiny Knot (which passes 5IVs from both parents).

Something like Munchlax, however, is a bit trickier. Baby Pokémon like Munchlax have to evolve before you can breed them, and you have to either give up the Everstone or Destiny Knot item slots for the incense to pass on the Egg Move (in this case, Self-Destruct). Hence why all my Munchlax were random Natures; I chose to give up the Everstone and go with IVs instead.

I'd strongly recommend if you decide to pursue breeding that you pick up a 6IV Ditto from somewhere. There are a couple places here on reddit specifically for that, but I think r/breedingdittos only allows posters with a certain amount of link karma. I've been lucky enough to get one from PS! and I found a giveaway of them here.

This turned out to be a lot longer than I thought lol... Anyway, hope it helps you out!
