Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
All "Dracoslayer" monsters on the field gain 300 ATK/DEF. You can only use each of the following effects of "Dragonic Pendulum" once per turn. If a Dragon "Dracoslayer" monster you control activates its effect (except during the Damage Step): You can target 1 card on the field; destroy it. If this card on the field is destroyed: You can either add to your hand or Special Summon 1 "Dracoslayer" or "Dracoverlord" monster from your Deck.
