Name:Volcanic Doomfire [ヴォルカニック・デビル]
Effect:This card cannot be Normal Summoned or Set. This card can only be Special Summoned by sending a face-up "Tri-Blaze
Accelerator" you control to the Graveyard. During your opponent's Battle Phase, your opponent must attack this monster with
any Attack Position monsters they control. When this card destroys a monster and sends it to the Graveyard, destroy all
monsters your opponent controls and inflict 500 damage to your opponent for each monster destroyed by this effect.
