[[Tom Bombadil]]'s second ability says: "...reveal cards from the top of your library until you reveal a Saga card. Put that card onto the battlefield and the rest on the bottom of your library in a random order".

What if the (remaining) library does not contain any Saga cards? I suppose Tom's controller won't lose the game because it says "reveal" and not "draw". Does it mean that the whole library ends up being revealed and then being ordered as the controller wishes?
