Originally introduced in Duelist Alliance, Shaddolls combine flip effects and fusion monsters to surprise opponents. Powered by the incredible Shaddoll Fusion spell card, which allows monsters from the deck to be summoned as fusion summons, Shaddolls can summon Shaddoll fusion monsters of all attributes while simultaneously activating powerful graveyard effects. The Structure Deck: Shaddoll Showdown offers new monsters that break the rules of a Shaddoll monster, a complete selection of cards needed to build a Shaddoll deck, and much more.
