Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 "Dual Avatar" monsters If this card is Special Summoned: You can target 1 Attack Position monster your opponent controls; destroy it, also this card cannot attack directly for the rest of this turn. You can only use this effect of "Dual Avatar Fists - Armored Ah-Gyo" once per turn. While you control a "Dual Avatar" Fusion Monster that was Fusion Summoned using an Effect Monster as material, all "Dual Avatar" Fusion Monsters you control gain 300 ATK/DEF.
