This is an easy Matchup even if they play Miracle , or Dragon Priest. You always keep Lightning Bolt to kill Northshire Cleric or Radiant Elemental , Earth Shock can be nice to counter cards like Divine Spirit + Inner Fire Combo or HP Buff . In this deck you play a lot of removal to clear the board without problems . Hex is nice on Faceless Shambler or Humongous Razorleaf . Priest can 't do anything about Malygos and Ysera especially when you play Ancestral Spirit .

This is the worst Matchup for the deck . Your win conditions is to get Y'Shaarj, Rage Unbound on early game with Barnes , or to heal yourself with 2x Tidal Surge on Alexstrasza and Hallazeal the Ascended with Volcano for 15 HP. Always clear stuff like Mana Wyrm , Arcanologist and Medivh's Valet to avoid early damage.

This is an easy matchup if they play aggro , you can just win this game with earth shock , lightning bolt on vicious fledgling or murloc warleader , maelstrom portal can be nice especially with bloodmage thalnos , lightning storm and volcano can be the cards that will let your opponent surrend at turn 5-6 . 

Pirate warrior can be easy if you start with cards like earth shock to counter something like Bloodsail Raider , Frothing Berserker and Southsea Captain or also Lightning Bolt , Maelstrom Portal and Lightning Storm ,you can also consider to keep Tidal Surge that is a nice tempo play and Earth Elemental with coin ;

Quest warrior shouldn't be hard , i recommend to keep cards like hex or earth shock and future sight for early game , in late game you should easy win with your big creatures buffed with ancestral spirit . If he play Sulfuras you should start attacking your opponents instead killing his creatures . 

easy matchup even if they play aggro or midrange . This deck have a lot of removal like Volcano that can clear a lot of opponent's cards , Earth Shock is nice to counter spikebridged steed or Blessing of Kings , i recommend to save at least 1 Hex for Tirion Fordring and another one maybe for Ragnaros , lightlord . Paladin always play sunkeeper tarim , so don't let them overextend the board . Earth Elemental is nice with Ancestral Spirit

i just played 1 game vs hunter and i won , i suggest to keep Earth Shock for Kindly Grandmother or Maelstrom Portal to counter hunter's start , save Hex for Savannah Highmane , Earth Elemental or White Eyes can help you to defend yourself in mid game and Tidal Surge can be a nice tempo play .

After mage this is the worst matchup if your opponent plays Quest , Miracle shouldn't be that hard cause you just need to save Earth Shock for Edwin VanCleef and Hex for Arcane Giant , cards like Volcano can win you the game . Vs quest i recommend to keep Devolve to slow down the combo cause he can't return to hand minions to evolve combos . Early Barnes with ysharaaj, rage unbound can win you the game , sometimes Volcano can save you but if your opponent will get an early quest it will be impossible to win . 

Shaman should be easy to beat , you just have to value your removal such as maelstrom portal , volcano , lightning storm . Earth shock is very nice against flametongue totem or mana tide totem . if your opponent play jade version keep hex for aya blackpaw and try to get the best value from every card , i recommend to play killing their creatures with yours.When you can try to play around bloodlust .
