Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is in your hand or GY (Quick Effect): You can banish 8 cards from the top of your Deck face-down; Special Summon this card. You can banish 3 cards from your Extra Deck face-down, then target 1 face-up monster on the field; destroy it. You can only use 1 "Gizmek Orochi, the Serpentron Sky Slasher" effect per turn, and only once that turn.
