To be noted that it doesn't have any downsides if your hand is empty, but you'd need a very specific build to make that work consistently, and it would rarely be a turn 1 discard. Between Duress, Thoughseize and Inquisition, I really don't see why this would make the cut.
Seems very situational. If you're on the play, it won't come down on T1. On the draw, you need to hope opponent has T1 Shaman or Rootwalla. Even if they do, it trades with Rootawalla or Vengevine and seems unlikely to connect.
Not sure against what other deck you'd bring that in, but against Survival it seems heh.
