[Oracle 2002/10/01] * This card allows you to put a creature card into play without playing it and while ignoring the colored mana requirements in its cost. [D'Angelo 2001/08/15] * Usable on Creature and Artifact Creature cards. [D'Angelo 2000/03/03] * The creature is considered to be a 0/1 colorless creature with no name, creature type, expansion symbol, or abilities, and a mana cost of 0. None of the true characteristics of the card apply. This is true as long as it is face down. [CompRules 2001/07/23 - 504.2] * The creature enters play face down, so none of its "comes into play" abilities will trigger or have any effect. [CompRules 2001/07/23 - 504.2] Also none of the "If this would come into play" abilities apply. [D'Angelo 2002/05/15] * The controller may turn it face up any time that player has priority. This action does not go on the stack. [CompRules 2001/07/23 - 504.3] * When turned face up, the creature regains its full characteristics. [CompRules 2001/07/23 - 504.4] * The creature's "comes into play" abilities (and any other abilities relating to the creature coming into play) do not trigger when it turns face up.
