Archetype: Tempo Midrange
Skill Cap: Above Average
With the advent of Murmuring Elemental, Shaman can now generate massive amounts of tempo multiple times in a single game.
Hobgoblin: Has synergy with Fire Fly, Flame Elemental, Stonehill Defender, Tar Creeper, Murmuring Elemental. Usually, you will want to save up these cards for a huge swing with Hobgoblin, unless you desperately need board presence.
Kalimos, Primal Lord: Extremely powerful when played with Murmuring Elemental. Very flexible. Can be used to deal 12 damage to face, deal 6 damage to all enemy minions, or restore 24 health to your Hero. You can even mix and match (eg. deal 3 damage to all enemy minions and restore 12 health to your Hero).
Servant of Kalimos: Can Discover Kalimos, Primal Lord/Al'Akir the Windlord/Blazecaller/Fire Elemental/Earth Elemental/Grumble, Worldshaker/Murmuring Elemental/Jade Spirit/Hot Spring Guardian/Stone Sentinel/Servant of Kalimos/Tar Creeper.
Murmuring Elemental: Insane synergy with Kalimos, Primal Lord, Blazecaller, Jade Chieftain, Aya Blackpaw, Jade Spirit, Jade Claws, Servant of Kalimos, Stonehill Defender. It is also an Elemental for the purpose of Elemental synergies. Can also be played with Hobgoblin in emergency situations.
Brann Bronzebeard: Insane synergy with Blazecaller, Aya Blackpaw, Jade Spirit, Jade Claws, Servant of Kalimos, Stonehill Defender and especially Jade Chieftain. You can also save Brann Bronzebeard for a huge turn after playing Grumble, Worldshaker.
Jade Lightning: Jade synergy. While this doesn't have Battlecry nor Elemental synergy, having another way to bypass Taunt is quite valuable.
Grumble, Worldshaker: If the opponent leaves any Murmuring Elemental/Jade Spirit/Aya Blackpaw/Jade Chieftain/Kalimos, Primal Lord/Blazecaller alive, this will make them severely regret it. It is also an Elemental for the purpose of Elemental synergies.
Tol'vir Stoneshaper: Very powerful when played on curve. Good anti-aggro tool.
Tar Creeper: Can be played alongside Hobgoblin as a 3/7 Taunt, that has 5 attack on the opponent's turn. It is also an Elemental for the purpose of Elemental synergies. Curves perfectly into Tol'vir Stoneshaper.
Stonehill Defender: Can be played alongside Hobgoblin as a 3/6 Taunt. Very high chance to Discover Al'Akir the Windlord/Thing from Below/Earth Elemental/Voodoo Hexxer/White Eyes/Drakkari Defender/Hot Spring Guardian.
Ragnaros the Firelord: Good in a Taunt heavy meta.
Fire Plume Harbinger: Can be used pull off a crazy combo with Grumble, Worldshaker. Also allows you to play 2 Hobgoblins and a ton of Elementals (Tar Creeper/Fire Fly/Flame Elemental) in a single turn.
