Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During your Main Phase, you can inflict 400 damage to your opponent for each face-up LIGHT monster you control. This card cannot attack during the same turn you activate this effect. Only one "Fairy Archer" can have its effect activated per turn.
