Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by sending 3 monsters you control to the Graveyard, and cannot be Special Summoned by other ways. When this card is Special Summoned: Toss a coin and gain the appropriate effect. ● Heads: When this card destroys an opponent's monster by battle and sends it to the Graveyard: You can target 1 card in your Graveyard; add that target to your hand. ● Tails: During either player's turn, when a Spell/Trap Card, or monster effect, that targets this card is activated: This card loses exactly 1000 ATK and you negate the activation, and if you do, destroy it.
