Any suggestions of a sub for Rat pack? Maybe Stitched Tracker?

Do you want to build a zombeast?

Ragnaros used to top off the pre-rotation midrange hunter as a finisher. I dont see why we wouldn't want The Lich King as a Dr. 8 in midrange now. I know what I don't want: 2/2s for 4. Arfus is actually a worse tempo card than Stitched Tracker and the Death Knight card might not even be useful every time. The risk of having it stolen by priest or just being way too slow is too high. I get the Corpse Widow reduction but that's still a 7 mana play and why aren't you running Nesting Roc instead? 1 less hp and NOT taunt for a chance at a decent turn somewhere in the mid to late game. I'm not seeing it.

It seems fine, but then you have to rename the deck from 'Slower Midrange' to 'Slow Midrange'

Edit: Also dont put in more deathrattles, the deck has enough deatchrattles already.

Same was said about rogue... It will see play.

i think ingame new deck recipe is much better than this one because secret hunter with rexxar DK is better because you can dump secrets and when starting to run out of steam can use new DK hero power to get a beats every turn. 

I don't think so. This deck is still predominantly midrange tempo, and Arfus is on the slower side in any case. I would swap in either Tundra Rhino,  or perhaps even test Bloodworm
