Murlocs can be exceptionally powerful when you hit the right synergies at the right times. This list from one of Holland’s best players, Thijs Molendijk, brings all those synergies together in one powerful deck.
It includes a few other tech cards -- such as Spirit Echo that returns all dead minions to your hand (which is great if you have no card draw in your deck). The finishing touch is Bloodlust, which can be used to quickly end the matchup in case you have enough Murlocs on board already.
If you’ve been watching Thijs’ streams, you've seen him finish the Murloc Quest in just a few turns, and then summon a gigantic Megafin on turn five. It’s too bad if the opponent has early AOEs to deal with your board -- but if you can dodge that bullet, then the victory is practically guaranteed.
