LivefromBenefitSt's review of the first Law of this set pretty much sums up why this might be the most annoying Treacheries in the game.
Fun fact for this particular card is that, if I'm not mistaken, this is the first instance of an effect that fundamentally changes the game depending on the language you are playing (card titles differ in word length in different languages). So for example Look what I found! is playable while you hold Pandemonium and can be discarded to get rid of it if you are playing the game in English; while it's the opposite (dead card in hand) if you are playing in Spanish ("¡Mira lo que he encontrado!").
Having arkham player cards in Polish, English and Italian it is really fun dealing with these encounter cards. I purposely take 1 italian and 1 polish copy of, let's say, Magnifying Glass (Lente di Ingradimento) and have some fun :D
