any replacement for subject 9 and snake trap?
Subject 9 is very strong in this deck since hunter doesn't have much card draw options, so I would recommend crafting it if you like secret hunter but you could replace it with Savannah Highmane and you could replace Snake Trap with another Explosive or Freezing trap. I would also recommend swapping 1 or both tracking with a Secret Plan just for more secret generation (at least until you could craft Subject 9). I personally don't like Tracking so I use 2 Secret Plans in their place.
Secret Hunter is a strong deck and a great choice for ladder right now! Here's a few games and a quick overview of the deck;(Games start at 5:58)Good luck out there!
