During the Main Phase, you can: Fusion Summon 1 "Shaddoll" Fusion Monster from your Extra Deck, by banishing Fusion Materials listed on it from your field or GY, but it cannot attack directly. Then, you can send to the GY 1 monster your opponent controls with the same Attribute as that Fusion Summoned monster. You can only use this effect of "Shaddoll Schism" once per turn.
