You can Tribute this card; add 1 "Uria, Lord of Searing Flames", "Hamon, Lord of Striking Thunder" or "Raviel, Lord of Phantasms" from your Deck or GY to your hand, then you can Special Summon 1 Level 10 Pyro, Thunder, or Fiend monster from your hand whose ATK equals its own DEF, ignoring its Summoning conditions, but it cannot attack directly this turn.
