Nehshaddoll Genius

FLIP: You can target 1 "Shaddoll" monster you control; that face-up monster is unaffected by monster effects this turn, except its own. If this card is sent to the GY by card effect: You can target 1 Effect Monster on the field; neither player can activate that target's effects on the field this turn. You can only use 1 "Nehshaddoll Genius" effect per turn, and only once that turn.
