Heroic Nightbane Miracle Rogue

Gameplan:

Use the 10 mana at the start to begin cycling through your deck as fast as possible. You'll eventually be able to pull massively powerful combos with Malygos and your spells. Mulligan for cards like Barnes, Gadgetzan Auctioneer, Sprint, and Thistle Tea. If you cannot build a sustainable card draw, restart. Be aware that Nightbane has at least 2 Deadly Shots and a Kill Command, which as far as I can tell are his only removal.

Early Game:

Beginning the game with card draw of any kind is extremely important. If you do not have Gadgetzan Auctioneer or Sprint, you can fish for a Gadgetzan Auctioneer with Barnes or your cycling cards. Draw into as many cards as possible and remove threats on the board when you can. Sap is particularly valuable for removing minions with Windfury or Ancestral Spirit. Avoid using Eviscerate and your second Shadow Strike and Preparation, since these are best used on Nightbane. Sometimes, you may be stranded without card draw due to an early Deadly Shot. Continue to hold the board and you'll probably be able to cycle into another Gadgetzan Auctioneer using Shiv, Sprint, or Fan of Knives. The goal is to have a hand ready to unload a tremendous amount of damage on Nightbane over 1 or 2 turns.

Late Game:

A few turns in, you may be running low on removal. It's okay to use your weapon to remove minions if you have to, as sometimes Nightbane will use Alexstrasza on your face even when you are low. Emperor Thaurissan will help you generate a stronger combo, if you have space to play him comfortably. On turns where you will still be alive without removal, use Malygos and your face damage spells. Shadowstep Malygos to prepare for a second barrage of spells if you need to. Conceal also works, but is less reliable due to Deadly Shot. Be careful about chaining many spells together at this stage in the game if you have Gadgetzan Auctioneer on the board; fatigue damage can cost you a victory.

Other Considerations:

• Bloodmage Thalnos could be extremely valuable here to soak up a Deadly Shot, cycle a card, and provide an extra boost of damage. You can replace Thistle Tea with Bloodmage Thalnos.
• A healing card, like Antique Healbot, could give you an extra turn to setup a damage combo.
• Cold Blood is another option for a cheap damage card, but it can be difficult to have minion ready to attack.
• Journey Below could also be used to cycle with Gadgetzan Auctioneer and possibly provide a taunt, but is likely too unreliable.
