Actually you will not be able to find a Groudon in pokemon black or white. It's because you will not be able to find a Groudon in the wild. The only way you can get Groudon in pokemon black and white you will have to trade with someone who has a Groudon or you can use Global trade.
Groudon is unavailable in heartgold. You can only catch Kyogre. If you want groudon, you will have to trade from heartgold, or migrate from another game.
