Hearthpwn

Simple yet effective tempo deck. Try to curve out well.

Mulligans are usually Swashburglar, Undercity Huckster, SI:7 Agent, Loot Hoarder, Defias Ringleader, Bloodmage Thalnos. Keep Unearthed Raptor if you have Undercity Huckster or Loot Hoarder in hand.

Always keep Defias Ringleader opening hand if you get coin. Drop SI:7 Agent on turn 3 if you have nothing else to play. Dropping a 2 mana minion on turn 3 is OK if you have Swashburglar + SI:7 Agent and no 4 drop for turn 4. 

Use your mana as efficiently as possible, while being aware of board clears. Do not be afraid of board clears either; it can lose you the game if you don't drop minions. Make sure you try to fill up on gas whenever possible. Avoid dropping Unearthed Raptor without a gas target.

This deck contains decent spell damage, use your spells wisely. 

Know when to go face. If you are ahead, trade only if you need to. Know when to go all in. 

Gas: Primary Unearthed Raptor target > Undercity Huckster Bloodmage Thalnos Loot Hoarder, Swashburglar,  Azure Drake 

Damage: Secondary Unearthed Raptor target > Southsea Squidface

Finisher: Southsea Deckhand > 2x Cold Blood > Faceless Manipulator = 20 damage.

Mulligan keeps (Try not to keep more than one spell in opening hand. Keep 1 of the mulligans, the rest of your opening hand should be 1 and 2 mana minions. Know when to keep backstab)

Shaman: Eviscerate, Shadow Strike, Sap, SI:7 Agent with coin

Warrior: Southsea Squidface, Tomb Pillager

Mage: Eviscerate, SI:7 Agent, Backstab, Shadow Strike

Know when to Faceless Manipulator a high value threat. I've won games manipulating Ragnaros the Firelord which delivered the lethal blow.
