I want to use the ARD to get Event Pokemon. Does anyone have codes?

Hey now, before you all call me a cheater I only got an AR to get the event Pokemon (like Shaymin) which are no longer available. This would mean that I am mostly looking for the codes which will give me the item to turn in (in the case of Shaymin, I would turn the item into Prof. Oak) to get the Pokemon. Any help is greatly appreciated. Website links would be great! Thanks!!!
