Updated Malygod Rogue! You can sub Antique Healbot for Earthen Ring Farseer, I just find the +5 more health saving my ass more times than I can count.
Edwin VanCleef: Shade of Naxx, Earthen Ring Farseer
Malygos: Oil Rogue
Bloodmage Thalnos: Kobald or Loot Hoarder, I use it for the spell damage so Kobald is better.
Loatheb: Sludge Belcher, Violet Teacher (?)
Emperor Thaurissan: This one's pretty difficult to replace, I'd suggest Sylvanas Windrunner, Dr. Boom, Gadgetzan Auctioneer (maybe), Sunwalker, Kel'Thuzad, basically any kind of win condition or replacement 6-drop.

"There has been a mix of Zoo, Handlock, and Demonlock, so this is by far the hardest mulligan. Zoo = Control. Handlock = Pressure them. Demonlock = Save saps for Void Caller Shenanigans."

Combos: (Without Thaurissan out)
Turn 10: Malygod (9) + Sinister Strike (1) + Prep + Sinister Strike (0) = 16 damage burst OR Eviscerate = 17 damage OR Blade Flurry for 14 damage.
(With Thaurissan out for 1 turn)
Turn 10: Malygos (8) + 2x Sinister Strike (0) + 2x Eviscerate (2) = 34 Damage wombo combo
That's basically it, maintain board control and pick off the oppenents face and BOOM MALYGOD IS IN THE HOOD READY TO BURST SOME FACES. Try it out!
Side note: I've found 2x Sprint is better than 1x Sprint and 1x Gadgetzan with an empty hand. Feel free to sub a Sprint for the best dealmaker in town if you wish.
