Although it requires Dead Reckoning cards, there are no regular Legendary cards which means its pretty cheap to make.
This deck brought me to Master after I had been stuck for much of the month at Diamond. I'm also having a lot of fun playing it.
It hits the meta at a pretty good spot as it has a good matchup against Feln Control and benefits from many of the same cards that make Feln Control so good. Also given that control meta is the main thing the ability to recur threats (often requiring them to be dealt with at instant speed) is very strong.
Note, In cold blood is best used against the creatures who silence.
