New version, got an insane 9-0.

This deck has 2 different win conditions:

1) Against Aggro: Secrets and spellstones
2) Against Control: Malygos Combo

Strategy:

1) Against aggro you need to survive early game, so search for Explosive Trap, Mad Scientist , Wandering Monster, Cloaked Huntress.
Since you don't need the spells for the combo, you can use them to remove minions, once you got the control of the board Lesser Emerald Spellstone and Deathstalker Rexxar will do the rest.

2) Against control Stitched Tracker will help you to find your win condition, usually you want to copy Subject 9, because he draws 5 cards, helping you to remove cards from the deck and find the core cards. If you already have combo pieces in hand, you can copy Emperor Thaurissan to discount your hand. Once you have all the pieces there are 3 different combos you can do, depending from enemy HP. 

Only Malygos  (+5 Spell Damage): 2 x Arcane Shot + 2 x Quick Shot = 30 Damage

Only Vereesa Windrunner   (+2 Spell Damage): 2 x Arcane Shot + 2 x Quick Shot = 18 Damage

Malygos  + Vereesa Windrunner  (+7 Spell Damage): 2 x Arcane Shot + 2 x Quick Shot = 38 Damage
