ha! It's...well its...you know kind of it's...
You know how when you encounter pokemon in the tall grass it "seems" that their nature/gender/level/IVs/ability are all RANDOMLY GENERATED? Well, infact, they're not. There's a pretty easy way to (without an AR, pokesav, whatever) to make them come out perfectly flawless every time. It's called "RNG abuse". It involves setting your DS Date and time to certain specific times and doing various things ingame like taking specific amounts of steps, etc... It's like poke-saving, but you don't use an AR or anything, just your game by itself.
