You can Special Summon this card (from your hand or Deck) by sending 1 face-up "Lyna the Light Charmer" and 1 face-up LIGHT monster from your Monster Zone to the GY. When Summoned this way: You can add 1 Spellcaster monster with 1500 DEF from your Deck to your hand, except "Familiar-Possessed - Lyna". If this card Special Summoned by its own effect attacks a Defense Position monster, inflict piercing battle damage. * The above text is unofficial and describes the card's functionality in the OCG.
