Hauptsicherungsschalter

Text:

2, : Tappe alle anderen Artefakte. Diese enttappen nicht während des Enttappsegments ihres Besitzers, solange der Hauptsicherungsschalter getappt bleibt.

Rulings:

• 10/4/2004 Note that you can’t choose to leave this card tapped during your untap step (unless some other effect says so).
• 10/4/2004 Only the artifacts that it tried to tap when the ability resolved are prevented from untapping. Artifacts that enter the battlefield after that or permanents that become artifacts after that are not affected.
