Were can i get free yugioh cards.....?

I don't know of any place/site that gives out free Yu-Gi-Oh cards. You can try Craigslist, but it's not likely you'll find people giving rare cards away, even if they don't use them. The site I've found best for buying cards, though is GatheringGround.com. It's prices aren't exactly a steal, but they're the best I've found so far.
