What you need:

1. Any DS/3DS

2. Any Gen IV and V game

3. Friend code

4. Any computer

5. ... that can access Pokedit.com

How it works:

"Another key feature of PokEdit is our GTS Service. This allows you to wirelessly send Pokemon from our website directly to your game. You can only send one at a time, so it's not as convient as buying an Unlocked Game, but it's a great way to get those Event Pokemon you missed. You can also send any Pokemon from one of our Databases or from the Editor." - from Pokedit

Use these Pokemon as they always worked for me!

Sounds really shady and unpleasant...I think I'll stick to not cheating :/

I know it sounds shady, but you are actually getting legitimate Pokemon that don't have unnatural stats , natures, IV, and EVs. This is why you can send them to X and Y.

And the special event Pokemon in their database are the exact and legitimate ones.

So you can always restrict yourself to getting those real legendary event Pokemon that are hard to get anyway!

Ye.. I doubt this is legit

Do I need a pokemon game other than my X or Y carts?

I sold my Black and White versions.

Yeah you need Black and White : (

You can send these Pokemon to Gen IV (Diamond/HeartGold/Etc) though. But you need Black/White and Pokemon Transporter and Bank to send these Pokemon to X and Y.

If you want we can trade since I am able to get any Pokemon from Gen I-V now : P

Does it work with black / white 2? I havent watched the video yet, but i might try it out later.

Yes! I was using it last night! Got all legendnaries from Gen I-V in my X and Y!

Nah, no big deal. I am still early in the game. Just wanted a Mew on my team since I've liked him since Blue/Red.

Holy shit... It actually worked. Thanks for sharing this video :)
