Boris is considered tier 1 for good reason. He's the strongest mid-range hero there is right now with early game control and ability to play into the late game. My deck varies slightly from others where I prefer using Fleet-footed Messenger over Tainted Oracle as an additional draw option to go with Bad Santa and Blood Frenzy as its lets me recycle extra copies of BF and lets me try to dig for Javelin and Tooth later.
