Once per turn, when this card destroys an opponent's monster by battle and sends it to the GY: You can Set 1 "Fire Formation" Spell directly from your Deck. Once per turn: You can send 1 face-up "Fire Formation" Spell/Trap you control to the GY, then target 1 Spell/Trap on the field; destroy that target.
