Aggro and Control in one deck? lol. Also I would add it to the budget hub. nice deck for only 47 bucks

Cool deck! I feel like you always want Noxious Gearhulk over Nightmare - your entire deck is focused around dwindling your opponent's resources. The Gearhulk deals with the threats your opponents manage to stick through your discard. While it won't be as big as a Nightmare, I think it will win you more games due to removal/lifegain. It's worth noting it also is a 5-power menace, which will realistically end the game just as well as an 8/8-9/9 flyer.

Also, I don't know what your budget looks like, but you should really play Fatal Push if you're in black - its price is only going to go up from here, you may as well get your playset asap ;). If you manage to get ahold of some, I would cut Cartouche of Ambition (too low impact) and Cruel Reality (too expensive for too low of an impact on turn 7+).

Good luck!

Yeah thanks -Arcanity- Ill add it there! Ooh yeah MStranger youre probably right, Ill get to adding more Noxious Gearhulks! Yeah the price on Fatal Push is certainly whats holding me back, Ill definitely look into it more though, thanks for the advice! :D
