Little bit of backstory: I have been playing Hs since GvG and I made a personal goal to get to legend with a deck of my own creation. I have basically played every expansion since GvG and gotten close but never over the top. The ravages of Demon Hunter almost took me out of HS altogether and I took a two month break right before Scholomance released. This break helped me a lot. I am 35 now and have been through a lot personally since I started playing. The break helped to clear my mind of bad habits and look at the game without knowing all of the Scholomance cards. I threw an initial version of this deck together around the second week of September and to my surprise, it was doing way better than I thought it would. I made some changes over many, many games and finally settled on a decent build that finally got me to legend for the first time. I was ecstatic. This is the creation. I even got two compliments on this deck from players on ladder.
tl;dr Wanted to make a deck of my own creation get to legend for the first time. Did it.
So, what does the deck do? Why some of the odd choices?
The MVP cards:
Devolving Missiles - This card will basically be the difference maker in most games. It disrupts opponents tribal syngeries (Pirates, Murlocs, Totems), and it a good card to use against Control Warlock and some combo decks.
Primordial Studies - This is the engine that makes the deck run. The best starting hand in general is: Black Cat, Primordial Studies, Unexpected Results.
1st Turn -Primordial Studies (if you don't have a Black Cat in hand and it's offered, take it) Also, don't be afraid to take a high health, low attack Spell Damage minion. Having it stay alive for a future turn can be a lifesaver.
2nd Turn - Black Cat for 2 (discount from Primordial Studies), 3/3 on Turn 2 that draws a card.
3rd turn - If Black Cat is still alive, Unexpected Results for two random three drops.
