Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card is activated: You can add 1 "War Rock" monster from your Deck to your hand. At the start of the Battle Phase, if you control no monsters, or all monsters you control are Warrior monsters: You can Special Summon 1 "War Rock" monster from your hand with a different name than the cards you control. If your Warrior monster would be destroyed by battle, you can send this card to the GY instead. You can only activate 1 "War Rock Mountain" per turn.
