This is a fast but consistent aggressive deck that I put together and it has worked very well. I'm not sure I'd change anything to be honest, although I have yet to pull Siraf from the market so that is probably cut-able. Also happens to be budget, especially if you cut Siraf then it has 0 legendaries. I don't have a ton of results yet but it has felt extremely good against the majority of the AI opponents.
Fearless Crescendo is a decent combat trick and can pull some powerful options like a
Wind Conjuring. It goes very well to force through damage on an Aegis unit. The Aegis units do very well against the AI removal and we run 8 pump spells to force through damage and blow out the AI.
Give it a try, best of luck!
Results:
7 win, sudden death with us going first
7 win, defender of the spire with us going first
0 win, loss to a great draw from hiding in darkness. I also badly misplayed the last turn at 2 life, holding up Commando for blocking forgetting that I was taking 2 damage on the start of turn for lethal (you take opponent's night damage, plus the extra damage at night curse). I was also stuck on 2 for quite a few turns. Game was definitely winnable without pilot error.
2 wins, loss to Midnight Storm absolute nut draw with chaining 3
Black-Sky Harbingers and ultimating Ancient of the Caves drawing 8 cards from an empty hand. I had 5 cards in hand at the time. Didn't draw removal in time.
7 wins beating highly skilled and destroying Midnight Storm in the rematch with our deck having a slightly below average draw and going second!
7 wins, beating mindless aggression (play conservatively to avoid getting blown out by infiltrate units) and beat Midnight Storm along the way with not too much difficulty as it double blocked my
Intrepid Longhorn with two 2/2 fliers and I pumped it up, killed both and got an undepleted power to make my 3 drops.
