I'm trying to make a working spell dmg deck with various classes since RoS release, due to some really nice cards that combo together. Till now, the only succesful ones (though still quite hard) are Rogue and Shaman. But after making some tries, i am now convinced that the class better designed for this kind of deck is Hunter, thanks to it's ability to deal with aggro, midrange and control decks.

Really easy concept:

Just go face with spells when you have spell damage active. Don't be scared though to use some of the them to deal with the threats, cause Zul'jin will recast them later. 

Acolyte of Pain and the 2 Spellbook Binder are core for the drawing, and remember you can use the latter ones also after attacking with Vereesa Windrunner's Thori'dal, due to having +2 spell dmg.

Use secrets to control the board (and remember both Explosive Trap and Snipe are augmented by spell dmg), toghether with Deadly Shot and Unleash the Beast.

Remember that Spellzerker must receive damage in order to gain spell dmg, so if you can't trade him for any reason, you can trigger him using one of Arcane Shot, Rapid Fire and Bomb Toss. However due to twinspell, the best of this options is Rapid Fire

In the deck there's no Animal Companion because i preferred to put only spells that deal damage (except for Freezing Trap, Rat Trap and Unleash the Beast, that are for board control), but this means that there are only 3 ways to summon beasts for your Kill Command:
- Unleash the Beast and its twinspell;
- An overkilling Baited Arrow;
- 2x Marked Shot giving you some other beast-summoning spells, but it's up to the RNG at that point;
So remember to use this wisely. Nonetheless, the spell damage gained from Vereesa Windrunner's Thori'dal and the spell damage minions can fill the gap and still grant you a high damaging spell. Also, the Violet Warden are crucial midgame for the taunt.

Zilliax has synergy with Bomb Toss, that also summons a mech, scaring people and almost always forcing them to do the job trading the bomb for you. If they don't cause they realize you're not a mech hunter, use the Ancient Mage to give them +1 spell damage making them a necessary target.

Zul'jin is the core for the endgame, notice that you'll receive a copy of every twinspell card you played (so both Rapid Fire and Unleash the Beast can be obtained).

IMPORTANT REMINDER: 
When you have Vereesa Windrunner's Thori'dal equipped, if you attack with it and then cast Zul'jin all of the spells will receive a +2 bonus dmg, in this deck that's huge. However, they have random targets, so be sure you don't risk to get killed by them. If everything works fine, you can easily deal 15 damage or more to the face in that turn. It has won me a bunch of games and it's really funny cause, also if not properly an OTK, it can smash the opponent's face also with some board down and unexpectedly.

I am having a lot of fun with this deck and i'm also performing quite well, but there's still some refinement to do so, if you want to suggest something, please do it!
Especially, i think there's a lack of taunt to deal with the most aggro decks around, so maybe i will think about re-inserting  Animal Companion, but still have to understand what to swap.

Enjoy
