When this card is Tribute Summoned while you control no Spell/Trap Cards: You can activate this effect, your opponent declares either Continuous Spell or Continuous Trap, then you Set 1 card of that type directly from your Deck. This card gains 300 ATK for each face-up Spell/Trap Card you control. Face-up cards in your Spell & Trap Zone cannot be destroyed by card effects.
