Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can banish this card from your Graveyard to target 1 face-up Xyz Monster you control with no Xyz Materials and 2 "Heraldic Beast" monsters in your Graveyard; attach those monsters from the Graveyard to that face-up Xyz Monster, as Xyz Materials. You can only use the effect of "Heraldic Beast Twin-Headed Eagle" once per turn.
