When your opponent activates a card or effect that targets a card(s) you control (Quick Effect): You can negate that effect, and if you do, destroy that card.

If this face-up Special Summoned card in its owner's control leaves the field because of an opponent's card: You can Special Summon 1 Level 11 or lower "Gate Guardian" monster from your Deck or Extra Deck, ignoring its Summoning conditions.
