If you want event Pokemon, download the actual Event, almost all of them will go through without fail. Event Pokemon sometimes carry moves they wouldn't know. Why you would hack one from scratch is beyond me.
If you really can't be bothered to EV train it, or teach it moves in-game, you can tweak it in Poke'Gen.
Bulbapedia has a good list of every Event Pokemon ever from every country. Find ones you like. A simple Google Search should be able to direct you to the PKM file. Download the file, and tweak it in Poke'Gen if you must, and then download it into your games.
Only problem I have had so far was some Shaymin, aside from that, the Pokemon will look as legit as Possible, as if it was just downloaded from the Official event yesterday.
