Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Insect monsters "Krawler" monsters this card points to cannot be destroyed by battle, gain 300 ATK/DEF, and if they battle your opponent's monster, any battle damage they inflict to your opponent is doubled. If this face-up card is destroyed by battle, or leaves the field because of an opponent's card effect while its owner controls it: You can target 2 "Krawler" monsters with different names in your GY; Special Summon them in face-down Defense Position.
