Luna the Dark Spirit — Ruling

Effetto 0

This card's effect that states it cannot be Normal Summoned/Set and must first be Special Summoned by its own procedure is not an effect. (Banishing a DARK monster from your Graveyard and Special Summoning this card do not happen simultaneously. Special Summoning this card with this procedure does not start a Chain.)
If this card is sent to the Graveyard after it was successfully Special Summoned from your hand by its own procedure, you can then Special Summon it from the Graveyard with Monster Reborn, etc.

This card's effect that inflicts 500 damage to your opponent is a Trigger Effect. (It does not target.)
This effect activates once during each of your Standby Phases.
