[StS] God the best I can do with the Watcher is halfway up Act 3.

I say that and then I clear act 3 with a Pressure Points build.

I had seven copies of Pressure Points in the deck by the end, and most of the rest was dedicated to card draw and scry

That and hopping in and out of Calm to get more energy

I had what can best be described as a straight damage race with the Time Eater and I won with multiple turns to spare.
