Activate only by sending 1 face-up "Blaze Accelerator" on your side of the field to the Graveyard. You can send 1 Pyro-Type monster from your hand to the Graveyard to destroy 1 monster your opponent controls and inflict 500 damage to your opponent, but you cannot declare an attack during this turn if you do.
