This card cannot be destroyed by the effects of Spell Cards. Once per turn, you can pay 500 Life Points to Special Summon 1 Level 4 or Pyro-Type monster from your Graveyard. Once, you can reveal the top 5 cards of your Deck. Shuffle them back in, and this card's maximum number of attacks this turn is equal to the number of Pyro-Type monsters revealed.
