Creature - Horror 3/4, 4B (5) {0}: If Eater of the Dead is tapped, untap it and remove target creature card in a graveyard from the game.1 Even the putrid muscles of the dead can provide strength to those loathsome enough to consume them.
Illus. Jesper Myrfors
A "creature card" is a Creature card or Artifact Creature card. [D'Angelo 1999/05/01] Older cards of type Summon are also Creature cards.
The card in the graveyard is removed from the game during resolution. [D'Angelo 1999/08/01]
It untaps during the resolution of its ability. [D'Angelo 1999/08/01]
It is not possible to empty a graveyard of creatures by using this effect repeatedly in one stack of abilities since the ability does nothing if the Eater is not tapped. [D'Angelo 1999/09/20]
It still untaps as normal during untap unless otherwise prevented. The ability is not inhibited by other effects that prevent normal untapping such as Meekstone, Paralyze, Smoke, etc. [Aahz 1994/08/10]
Extended tournaments (see Rule 803) have banned this card since 1999/10/01.
Note - This card was of creature type "Eater" until Oracle 2007/09/01 when it became "Horror".
