I was happy that i got wonder traded a 31/31/31/0/31/31 jolly darumaka till i realised it had its hidden ability (meaning it will be zen mode). So i bred it with a 2iv ditto and the first egg was 31/31/31/0/31/31 jolly with non-hidden ability.
I also managed to get a 31/31/31/0/31/31 adamnt weedle, from a 31/x/31/x/x/31 kakuna and 31/31/x/x/31/x ditto, in two eggs.
Lastly i took the pain of trying to breed 4 egg moves to a karrablast (pursuit, knock off, drill run, megahorn) and the original had only 31 defence. Unfortunately, because it was male, i had to breed it with a ditto (my best is 3x 31 in hp, atk and spdef) and i managed to get a 31/31/31/x/x/31 the first egg. Somehow i managed to get lucky with speed which was helpful as i had to get the egg before it grew 4 levels and learn another move (srsly, there should be a way to prevent certain moves from being forgotten)
That was all lucky, but when breeding charmanders, it took me over 150 eggs to get a 5iv one from 2 4iv parents.
When catching moltres, the first time i got timid (from synchronise) with 31/x/31/31/x/31. Unfortunately i didnt try with zygarde or mewtwo
