Card Rulings:Type Zero Magic Crusher


 * [Re: Ancient Gear Cannon] While "Ancient Gear Cannon's" effect is active, you can still activate the effect of a Continuous Trap Card that was already face-up, such as "Type Zero Magic Crusher". But you cannot activate (flip face-up) any more Trap Cards.


 * [Re: Gravekeeper's Watcher] You cannot activate "Gravekeeper's Watcher" when a card is discarded as a cost, such as "Magic Jammer", "Kuriboh", "Tribute to the Doomed", "Thunder Dragon", or "Type Zero Magic Crusher".


 * [Re: Mirage Dragon] The effect of this monster makes your opponent unable to activate Set Trap Cards. However, your opponent can still activate the effects of face-up Trap Cards such as "Type Zero Magic Crusher", "Ultimate Offering", "Skull Lair", "The Dragon's Bead", and "Astral Barrier".
