Card Text
If a non-Effect Monster is Special Summoned face-up (except during the Damage Step): You can target 1 card your opponent controls; destroy it. If this card in its owner's Spell & Trap Zone is destroyed by an opponent's card effect: You can Special Summon 1 non-Effect Monster from your hand, Deck, or GY. You can only use each effect of "Supernatural Danger Zone" once per turn.
