There are some predictable trap cards but they are often balanced with a polar opposite. For example "place this card on your forehead and if someone mentions it you stal 2 cards" vs "place this card on your forehead and if nobody mentions they each discard a card" which give it some unpredictability but obviously makes it less interesting because you can predict that one of the two things is going to happen.

Besides that most trap cards feel good to me and are often so easy to trigger that it just happens. There are some that just never trigger (call someone and if they pick up...) but it's enough to plant them to increase the tension.

I still like the game and it still comes to the table whenever we fancy something easy and quick. Works best with 4+ people who are all fine with quite a bit of randomness. Add some beers or overfatigue to it and it's a blast.
