Creature — Zombie 2/2, 3B (4)
Common
Madness {1}{B} (If you discard this card, you may cast it for its madness cost instead of putting it into your graveyard.)
When Grave Scrabbler enters the battlefield, if its madness cost was paid, you may return target creature card from a graveyard to its owner's hand.

5/1/2007: You can return a card in a different player's graveyard to that player's hand.
