Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn: You can target 1 Attack Position opponent's monster; change it to Defense Position, and if you do, for the rest of this turn, your monsters cannot attack, except to attack that monster, and if your Cyberse monster attacks a Defense Position monster, inflict piercing battle damage to your opponent.
