During your opponent's Main Phase, you can send this card from your hand to the Graveyard to select 1 face-up Effect Monster your opponent controls. Negate the effect(s) of that monster until the End Phase.
-This card will negate effects that activate or apply on the field. It will not negate an effect that activates in the Graveyard.
-If you control the targeted monster when the effect of Effect Veiler resolves, the targeted monster's effect(s) will not be negated.
-If the targeted monster is no longer face-up on the field when Effect Veiler's effect resolves, the targeted monster's effect(s) will not be negated.
-If the effect of Effect Veiler resolves, and the targeted monster is then flipped face-down, its effect(s) will no longer be negated, even if it is flipped face-up again later that turn.
-If you target Exiled Force with Effect Veiler and your opponent Tributes Exiled Force to activate its effect later in the turn, the effect of Exiled Force will be negated
