Text (SM): Enchant player. ; If a card would be put into enchanted player's graveyard from anywhere, instead that card is revealed and put on the bottom of that player's library.
It does not affect tokens or copies of spells that go to the graveyard since they are not cards. [Shadowmoor FAQ 2008/04/21]
If multiple cards would go to the graveyard at the same time, the owner of the library chooses the order that they go on the bottom of the library. [Shadowmoor FAQ 2008/04/21]
