Fill the opponent's void with cards via hunt and forced discards, then devour them with Collector Crow. I originally had Terrorclaw in the deck, but it felt too slow and didn't fit well into the power curve. I am currently playing Living Reflection for the added benefit of hunting, but Mirror Image is another option.
Update: Added Preyscouter and adjusted some of the other card numbers to make room for it.
Preyscouter could also work in this deck. I had been avoiding it because it used to be bugged, but now that it's fixed it would be worth trying.
