The power of this Side Scheme for Daredevil cannot be overstated.
Before getting into the benefits, let's just deal with the mechanics.
First, it is 0 cost, so you can throw it out there no questions asked. Second, it has a set amount to thwart that is independent of player count. (though that is largely due to the fact that only the Daredevil player can THW it.) Third, there's no victory reward, so you can use it repeatedly.
As for the benefit...I just don't know where to start.
The five cards in the sense deck are interesting and beneficial in and of themselves, but when you start to deal with combinations, the possibilities spiral wildly.
This is the fun, but very precarious implementation of Daredevil's Sense deck. It can truly turn the tide, so long as you are perpetually aware of it and take advantage of every opportunity to abuse it.
If it wasn't obvious, I loved Daredevil long before Fantasy Flight finally decided to add him to the game.
