Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you control no cards, except "Numeron Wall(s)" (Quick Effect): You can send this card from your hand or field to the GY; activate 1 "Numeron Network" directly from your hand or Deck. You can only use this effect of "Numeron Wall" once per turn. When you take battle damage: You can Special Summon this card from your hand, and if you do, end the Battle Phase after the Damage Step.
