Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you have a face-up Pendulum Monster in your Extra Deck, you can Special Summon this card (from your hand). You can only Special Summon "Nemleria Dream Defender - Couette" once per turn this way. When your opponent activates a card or effect that targets a "Nemleria" card(s) you control, while you have "Dreaming Nemleria" face-up in your Extra Deck (Quick Effect): You can banish 1 face-down card from your Extra Deck, face-down; negate that activation. You can only use this effect of "Nemleria Dream Defender - Couette" once per turn.
