Crystal Keep Rulings Summaries

• Only prevents the artifact from untapping during untap step. Ones that untap during upkeep are not inhibited. [Aahz 1994/06/01]
• Can target a tapped artifact. [Duelist Magazine #5, Page 22]
• The target artifact cannot untap if the Gremlins and the artifact are tapped during untap, even if it is your artifact, and you plan on untapping the Gremlins. [Aahz 1994/06/06]
• If the Gremlins somehow become an artifact and then tap themselves, they can never be untapped during the untap phase. They must be untapped by an external effect. [Aahz 1994/06/06]
• The effect does not end if the target stops being valid. For example, if it stops being an artifact. [WotC Rules Team 1995/02/09]
• Extended tournaments (see Rule 803) have always banned this card.
• Note - This card was creature type "Gremlin" until Oracle 2008/01/01, when it became "Ouphe".
