Card effect (current official text)This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by sending 2 Spell or Trap Cards you control to the Graveyard. You can destroy 1 Spell or Trap Card your opponent controls. If you activate this effect, this card cannot attack during this turn.
Rulings
- If you already can't attack, you can't activate this effect. This means that you can't activate this effect on the fist turn, and you can't activate it if this effect has already been activate this turn.
- The only way you can Special Summon this card is via its own procedure. Even if it was initially summoned that way, you still can't summon it with card effects.
