I'm going to try and see if I can use my action replay to get male-exclusive/genderless Pokemon with their hidden abilities in Black/White to transfer them to X/Y, but I need a little help.
The way the code works is that I need to subtract a number of Pokeballs from my bag, so that the remaining number matches the National Dex number of the Pokemon I'm trying to catch.
I'm not familiar with many of the National Dex numbers, so I need to know the National Dex numbers of all Male-exclusive/Genderless Pokemon that:
Isn't Ditto but can breed with one
Isn't a legendary
Has a hidden ability
I'm hopless at maths, so I guess I need to know the number of Pokeballs (from 649) that I need to subtract to get the Pokemon I need.
I can use Pokesav to change the location that the Pokemon were caught to Dream World, so Bank shouldn't consider them illegitimate.
Edit: Discovered that Beldum has a hidden ability, maybe I was getting confused with something else.
I was getting it mixed up with Rotom.
