Skill Cap: Above Average
This deck tries to stick as many Taunt minions on board, buffing them up with Mark of the Lotus and/or Strongshell Scavenger.
Failing that, you can either stall with Taunts until you have enough Mana to pull off a huge swing with Hobgoblin/Strongshell Scavenger in a single turn, or Spreading Plague.
The deck also has powerful Elemental synergy with Tol'vir Stoneshaper and Blazecaller.
Strongshell Scavenger: Usually you will want to refrain from playing this until you have multiple Taunts on board, but can be used to buff a single Taunt minion in desperate situations.
Hobgoblin: Has synergy with Crypt Lord, Annoy-o-Tron, Stonehill Defender, Tar Creeper, Fire Fly, Flame Elemental.
Crypt Lord: A very sticky Taunt that will usually force the opponent to waste removal on it to kill it. When played alongside Hobgoblin/Strongshell Scavenger, it becomes a 3/8 that grows.
Annoy-o-Tron: Can be played alongside Hobgoblin/Strongshell Scavenger as a 3/4 Taunt, Divine Shield minion.
Tar Creeper: Can be played alongside Hobgoblin/Strongshell Scavenger 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/Strongshell Scavenger as a 3/6 Taunt. Discovers even more Taunts.
Tol'vir Stoneshaper: Very powerful when played on curve. It will usually survive for more than a turn, allowing it to be buffed by Strongshell Scavenger.
Void Ripper: Allows you to burst down the opponent from high health, if you have a board full of high health minions. Can also be used to destroy Doomsayer or Totems.
Mark of the Lotus: Used to buff your board.
Spreading Plague: Allows you to catch up from behind. Scarab Beetle can be buffed with Strongshell Scavenger.
Wax Elemental: Cheap Taunt minion that can be buffed by Strongshell Scavenger into a 2/4 Taunt, Divine Shield minion. Can also be used to activate Elemental synergy.
Brann Bronzebeard: Strongshell Scavenger, Blazecaller, Saronite Chain Gang synergy.
Saronite Chain Gang: Generates 2 Taunt minions with a single card. Great synergy with Strongshell Scavenger, Crypt Lord, Brann Bronzebeard.
Sludge Belcher: Deathrattle generates another Taunt minion. Great synergy with Strongshell Scavenger, Crypt Lord.
Blazecaller: Very powerful Elemental synergy card. Can be played with Brann Bronzebeard to deal 10 damage to a single target.
Fire Fly: Generates Flame Elemental, which can be played alongside Hobgoblin as a 3/4 body, or used to activate Elemental synergies.
Igneous Elemental: Generates Flame Elementals, which can be played alongside Hobgoblin as a 3/4 body, or used to activate Elemental synergies. Curves perfectly into Tol'vir Stoneshaper.
Druid of the Swarm: Very strong and flexible 2-Cost Taunt minion. Unfortunately it doesn't work with Hobgoblin because it transforms after the buff.
Cenarius: Flexible card that can be used to buff an existing board, or summon Treants with Taunt that can be buffed with Strongshell Scavenger if they survive.
Malfurion the Pestilent: Overall powerful and flexible card. Can summon Scarab Beetles with Taunts that can be buffed with Strongshell Scavenger if they survive.
Sunfury Protector/Defender of Argus: Gives other minions Taunt, so that they can be buffed by Strongshell Scavenger.
Unstable Ghoul: Can be played alongside Hobgoblin as a 3/5 Taunt.
Gnomeregan Infantry: This minion's Charge can be pretty powerful if it is buffed with Hobgoblin/Strongshell Scavenger.
Arcanosmith: Taunt minion with Crypt Lord synergy.
Bonemare: Can be used to give another minion Taunt. Very strong card on its own.
The Lich King: Very strong Taunt minion.
Servant of Kalimos: Elemental synergy. Excluded because Druid doesn't have any class Elementals that are strong in this deck.
Thunder Lizard: Elemental synergy. Reduces the downside of rolling Taunt.
