They'll typically manage to play a nymph once, maybe twice (since you are busting their pillars, nymphs are expensive and they are not drawing more quanta, as the draw lock lasts while they have pillars left). Unless you get a late eternity they won't get a lot of quanta out anyway and if it is coming late your best chance is to try to rush with nymphs in the usual way, even though it's not as funny.
