MTG Crucible of Worlds Help?

Dr. Pepper is absolutely right. I just wanted to add that the reason they changed the wording is that the added "as if they were in your hand" part of the original card text confused some people, making them think that they could "discard" lands from their graveyard when someone forced them to discard, that they counted as part of their hand size, and so on, none of which is true. So they streamlined the text to make it clearer that the only thing you can do with Crucible of Worlds is put a land card each turn from your graveyard into play. And like Pepper said, it still counts as your one land that you can play that turn.
