Shadow-Weaving Power

This Skill's second effect can only be used once per Duel if all of the monsters in your Deck (excluding the Extra Deck) are "Shaddoll" monsters or Spellcaster monsters. 1: At the beginning of the Duel, choose 2 "Shaddoll" Trap Cards from your Deck at random and send them to the Graveyard, and add 1 "El Shaddoll Winda" to your Extra Deck, and 3 "Shaddoll Fusion" and 1 "Shaddoll Schism" to your Deck. 2: During your Main Phase, shuffle 1 "Shaddoll" card from your Graveyard or among your banished cards into the Deck.
