Introduction:

This Spell Hunter deck makes use of the new exciting cards from Rastakhan's Rumble, most notibly Zul'jin. Although Baited Arrow has it limited uses, it really helps out in this deck. 

A more in-depth guide could come if people request it in the comments, although this deck is pretty straight forward. 

Mulligan:

Against Aggro:

Candleshot gives you a great tool for one-health minions, and works fine to get favorable trades early game. With Hunter's Mark, you get great value.

Explosive Trap needs no introduction against aggro decks. 

Wandering Monster could give you the low roll with a 3/1, but it's still a trade. If you get a high-health minion, you can make two or three trades with it.

Animal Companion could be kept if you have some of the cards above. Cross your fingers not to get Huffer. 

Eaglehorn Bow could be kept if you are going against a deck with 3 health minions. 

Against basically anything else:

Animal Companion, Eaglehorn Bow, Wandering Monster and Flanking Strike could all be kept. 

If you have atleast two of the cards above, keeping Deathstalker Rexxar could give you the mid-game advantage. 

Lesser Emerald Spellstone could be worth keeping if you have one or two traps. 

 

Strategy and some card explanations: 

This deck uses a combination of board control, board cleard and, well, card combinations. If you survive and keep a relatively good board- and healthstate in the later game, your Deathstalker Rexxar, Zul'jin and Rhok'delar could all win you the game. 

Candleshot and Hunter's Mark are obviously used to remove anything your opponent puts down. 

Unleash the Hounds on it's own doesn't give you that much value, but in combination with Animal Companion or To My Side! you can usually trade favorably. It could also be used in combination with Baited Arrow for getting a big minion down and getting that valuable 5/5. 

Crushing Walls is really a hit or miss. If your opponent can play around it, it will not give you too much value. If he/she does not, you can essentially clear the board of big minions. In combination with Zul'jin, you can almost guarantee a board clear (as long as you used some other spells that targets minions). 

Zul'jin is a card you have to think about before using. Not only does it use up all of your mana (except one if you used The Coin earlier in the game), but the randomness of what your spells target could be devastating. A bad RNG with spells like Kill Command or Baited Arrow could kill you. If you used Unleash the Hounds in the game, keep in mind that it could fill up your board with 1/1 minions instead of your Animal Companions, Wolfs and 5/5 from Baited Arrow.
