Hello it's my first deck here, i've reached rank 5 with this deck, without any problems.
All new shaman decks are based on jade golems or evolve, but i remember the midrange shaman before the Gadgetzan expansion and it was pretty strong, and it still is. General change is Jinyou Waterspeaker, which gives u a strong heal - very helpful against aggro-cancer decks.
For +20 likes i will do a guide for this deck (mulligan, strategy)
It isn't my own deck i was watching a lot of pro players who played with similar or same decks!
Ok deck has reached +20 likes so here is mulligan:
In every match-up you need to keep Tunnel Trogg, Totem Golem, Spirit Claws also in specific match-ups you can keep Feral Spirit or Lightning Bolt (very useful against other shaman decks to destroy fast their trogg)
General strategy with this deck is to get early board control with cards like Totem Golem, Feral Spirit, Barnes and Thing from Below. Another key is to prepare combo with your Bloodlust. Try to keep Bloodmage Thalnos for boosting your spell damage card, it's very important to throw good Maelstrom Portal or Lightning Storm. Also Lightning Bolt with 4 damage can easily kill Azure Drake, Tomb Pillager or Blackwing Corruptor
Renolock, Renomage - You need to win as fast as possible so good mulligan is very important, renolock has a lot of removals so you need a little bit of luck as well.
Dragon Priest - The worst match-up, it's very hard to battle with his taunts and of course Dragonfire Potion one of the most op cards from gadgetzan expansion, which can clear your board easily.
Miracle Rogue - Easy Match-up you need to always kill his Gadgetzan Auctioneer, be careful about his combo with Cold Blood, you can keep Lightning Storm to clear his stealth minions. Use Hex on his Tomb Pillager.
Jade Druid - Easy Match-up too, this deck has the strongest late game but very weak early game, so gain board control asap and dont trade too much with late golems, always kill his Azure Drake cause combo with Swipe is very good. Prepare a lot of minions for Bloodlust combo.
Al'Akir the Windlord - Ragnaros the Firelord or Leeroy Jenkins for finishing
Bloodmage Thalnos - Kobold Geomancer
Barnes - Hard for replace because of very special effect, buy Karazhan :D
If you are not afraid of aggro-cancer you can replace your Jinyu Waterspeaker for White Eyes(for better late game) or Ragnaros the Firelord or anotherBloodlust
