Shamans are the masters of elements using their hero power to cast a random totem includes: Healing Totem, Searing Totem, Stoneclaw Totem and Wrath of Air Totem. There are many strategies to play with shaman decks such as having a large minions count as well as totems on the field and buffing them up with Raid Leader (3 to cast 2/2, Your other minions have +1 Attack) or Bloodlust (Give your minions +3 attack this turn). These cards has proven useful when it comes to doing some serious damage.
A shaman is not only efficient at dealing damage with minions, it is also effective at crowd control or board control. With cards like Hex, Lightning Storm, Forked Lightning and Lightning Bolt it makes Shaman versatile and deadly. Shamans are also known to have the “Overload” abilities in their cards, that allows them to cast spells at a really low initial cost meaning Shamans can burst down any targets really quickly and gain control.
The Shaman deck suits players who doesn’t mind being slightly behind at the beginning. The playing style would be defensive, removing any possible early game threats and progressively becoming more aggressive by mid game. Shamans should constantly cast totems to keep the minions count up and attack when it matters.
Once the Shaman has enough Mana, minions and totems on the board, it will be difficult to stop.
