Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Special Summon this card as an Effect Monster (Spellcaster/DARK/Level 9/ATK 1450/DEF 1950). (This card is also still a Trap.) If Summoned this way, this card can be used as a substitute for any 1 Fusion Material that lists an Attribute, on a "Shaddoll" Fusion Monster Card. If this card is sent to the GY by a card effect: You can target 1 "Shaddoll" Spell/Trap in your GY, except "Shaddoll Core"; add it to your hand. * The above text is unofficial and describes the card's functionality in the OCG.
