Sorcery, 2BB (4) Remove All Hallow's Eve from the game with two scream counters on it. At the beginning of your upkeep, if All Hallow's Eve is removed from the game with a scream counter on it, remove a scream counter from it. If there are no more scream counters on it, put it into your graveyard and each player returns all creature cards from his or her graveyard to play.1

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 creatures are put into play by their respective players, but they enter play simultaneously. For purposes of ordering any effects of the creatures, the current player (not the controller of this card) decides the ordering regardless of which player is putting the creatures into play. [D'Angelo 2000/03/03]
Two Legends of the same names that enter play are considered to enter play at the same time and both are destroyed. See Rule G12.9. [D'Angelo 2000/03/03]
Since you can respond to triggered abilities, it is legal to sacrifice creatures using some spell or ability prior to resolving the ability that removes the final counter from All Hallow's Eve. [D'Angelo 2000/03/03]
Extended tournaments (see Rule 803) have always banned this card.
