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 controlling 2 or more Zombie monsters. If this card is Special Summoned: Shuffle as many other monsters on the field as possible into the Deck, and if you do, this card's ATK becomes 1000 x the number of face-up monsters shuffled into the Deck this way, whose original Type was Zombie.
