Corpsetaker is a powerful card from Knights of the Frozen Throne, held back by a critical lack of minions with the desired keywords; ones that you would put in your deck, at least. With the upcoming Standard rotation and the printing of some interesting cards in the Witchwood, now is the best time for a deck based around Corpsetaker to emerge.
This is my take on the Midrange Hunter archetype, built around Corpsetaker and a draw engine featuring Countess Ashmore , Tol'vir Warden , and Dire Frenzy . Dire Frenzy shuffles buffed copies of Swamp Leech and Young Dragonhawk back into your deck to give Corpsetaker more opportunities to have as many keywords as possible, and Tol'vir Warden draws these buffed copies to immediately contest the board. Stitched Tracker fishes out the key minions in the deck like Houndmaster Shaw to regain initiative, and Deathstalker Rexxar provides the deck with a late-game win condition.
