Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When a card or effect is activated that targets this card (Quick Effect): You can Special Summon 1 "Blue-Eyes White Dragon" from your hand, Deck, or GY. When this card is targeted for an attack: You can negate the attack, and if you do, change the battle position of this card, then you can Special Summon 1 "Blue-Eyes White Dragon" from your hand, Deck, or GY. You can only use 1 "Maiden with Eyes of Blue" effect per turn, and only once that turn.
