You can select 1 face-up Effect Monster on the field if it's not already selected by this card. While this card is face-up on your side of the field, the selected monster's effect is negated until it is removed from the field. (You can select up to 1 monster at a time with this effect.) This card returns to the Fusion Deck during the End Phase.
