Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card is Normal Summoned: You can add 1 "Silent Swordsman LV3" or "Silent Magician LV4" from your Deck to your hand. During either player's turn, when a Spell Card is activated that targets exactly 1 monster you control (and no other cards): You can negate the activation. This effect can only be used once while this card is face-up on the field. If this card is destroyed by battle, or if this card in its owner's control is destroyed by an opponent's card effect: You can target 1 LIGHT "LV" monster in your Graveyard; add it to your hand.
