Once per turn, if a Spell/Trap Card or effect is activated (except during the Damage Step): You can draw 1 card, then if it was a Spell/Trap, you can Set it, and if it was a Trap or Quick-Play Spell, you can activate it this turn. If this card is destroyed: You can Special Summon both 1 "Dark Magician" and 1 "Dark Magician Girl" from your hand, Deck, and/or GY.
