Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
This card's name becomes "Fallen of Albaz" while on the field or in the GY. While a Level 8 Fusion Monster is in your GY, this card gains 200 ATK for each monster in your GY, also your opponent cannot target other monsters you control with card effects. If a monster(s) you control leaves the field by an opponent's card effect, while this card and a Fusion Monster are in your GY (except during the Damage Step): You can Special Summon this card. You can only use this effect of "Albaz the Ashen" once per turn.
