Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Pyro monsters If this card is Fusion Summoned: You can target 1 Field Spell in your GY; add it to your hand. At the start of the Damage Step, if this card battles an opponent's Pyro monster: You can destroy that opponent's monster, and if it is your turn, this card can make a second attack in a row. You can only use each effect of "Embers of the Ashened" once per turn.
