Update 1: As I feared, the deck flounders a bit in the mid-game if you haven't already won with early murlocs. To help mediate this, I've now removed Magicfin and Wriggling Horror and added 2 Voracious Readers, which has helped reload on cards in the mid-game.
The C'Thun Pieces can sometimes get in the way with emptying your had for the Readers, but even drawing 1 card vs top-decking a Wriggling Horror feels much better. And so far just having health buffs from Coldlight Seer has felt good enough even without the Wriggling Horror.
OK OK! I know this seems like a bazar combination, but just hear me out:---
The majority of this deck is dedicated to early game murlocs to fight for the board, and potentially just win by going full agro.
There are some powerful turns you can take with cards like
Lightning Bloom + Firemancer Flurgl + murlocs
Lightning Bloom + Nofin Can Stop Us.
However, there are some control matchups like Warlock that will be able to just clear all your murlocs. That's why this deck has a secondary win condition that also lets you transition to a more late game value playstyle. C'Thun, the Shattered will give you 4 decent control cards that will work toward a big game finisher if your murlocs run out of steam. Primordial Protector is able to not only tutor out your C'Thun peices, but also generate a 5 mana minion for tempo. And this late-game playstyle can be achieved by simply dedicating 3 cards to a non-aggressive game plan.
There are also cards included that are flexible at any stage of the game. In the early game Primordial Studies can find you a Novice Zapper or Lady Vashj, or in the late game you can try to find Steward of Scrolls.
Instructor Fireheart can be used as a finisher or a way to swing the board back in your favor.
Magicfin is situational, but can also reload your hand with a few potential Legendaries.
And then of course there is the new Kazakus, Golem Shaper who can fit any role, and was the reason I wanted to build a Murloc deck in the first place lol
There's even some upside with Eye of C'Thun giving you another finisher in an agro scenario!
It may seem odd, but I think this has some potential :)
