In the end this deck can be an OTK deck, but you can win earlier too. The absolute win condition is Anyfin Can Happen. Especially the second one. The combination of Bluegill Warrior, Old Murk-Eye and Murloc Warleader can be up to 38 damage. But always more than 30. This means lethal.

So the goal is just getting there. A couple of tools help to control the board, to stay alive and to draw cards. Especially The Curator is very important for card draw. You can even consider keeping this card in your mulligan. The Azure Drake and Bloodmage Thalnos provide additional card draw. However they even make your Consecration a lot stronger to deal with aggressive decks.

Not only Consecration, as well the Doomsayer and Aldor Peacekeeper are very useful to destroy and to extend the opponents play. And for the case of a very strong board the combo Wild Pyromancer and Equality is very powerful. 

Use your weapons Truesilver Champion and Tirion Fordring for your board control or to threaten lethal. But keep in mind you always have the win condition Anyfin Can Happen. For this deck it is way better to control the board than pushing face damage. The charge murlocs (Bluegill Warrior and Old Murk-Eye) are useful for this matter too. And it is always better they die than having them transformed into something different (Polymorph,Hex).

Ragnaros, Lightlord, Ivory Knight and Forbidden Healing heal you up. And Ivory Knight can be super useful to get a third or fourth Anyfin Can Happen or further card draw.

Spikeridged Steed and Tirion Fordring are probably the worst cards in this deck and can be exchanged. But in the aggressive small minion based meta they are super useful to get to your win condition.

Enjoy!
