[[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?
Because the effect puts them in a random order you don’t get to stack your deck. If you have no sagas in the deck you effectively just shuffle the deck with no other game effects.
With the added bonus of having your whole library revealed, making it possible for your opponent to deduce your hand via POE!
