The Golden Swordsoul

“When a monster declares an attack: You can Special Summon this card from your hand, and if you do, negate that attack, then, if you control a Fusion Monster that mentions "Fallen of Albaz" as material, you can destroy the monster that declared that attack. If a monster is banished face-up (except during the Damage Step): You can banish this card from your field or GY; Special Summon 1 LIGHT Spellcaster monster from your hand or GY whose ATK equals its own DEF. You can only use this effect of "The Golden Swordsoul" once per turn.”
