Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 DARK Fusion Monster + 1 Fusion Monster (This card is always treated as a "Predaplant" card.) Once per turn, when a card or effect is activated (Quick Effect): You can Tribute 1 monster on either field with a Predator Counter, and if you do, negate the activation. If this Fusion Summoned card you control is sent to your GY by an opponent's card: You can target 1 DARK monster in your GY; Special Summon it. You can only use this effect of "Starving Venom Predapower Fusion Dragon" once per turn.
