Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
"Naturia Beast" + "Naturia Barkion" A Fusion Summon of this card can only be done with the above Fusion Materials. When a Spell/Trap Card is activated (Quick Effect): You can banish 1 card from your GY, then send the top card of your Deck to the GY; negate the activation, and if you do, destroy that card. This card must be face-up on the field to activate and to resolve this effect.
