Cthun Quest Lock

This deck revolves around drawing, removing threats and developing defensive units while working towards a few different win conditions like discounting big threats, playing Cthun or fatiguing your opponent with multiple Tickatus’s. Its particularly weak against Demon Hunter and sometimes struggles against Warlock Tickatus decks. There is an additional minor synergy between the Amalgam and Nether Breath which may or may not be worth including.. I find the additional healing / removal is helpful sometimes. Here are the main win conditions:

-Discard your opponent into fatigue with multiple [occasionally discounted] Tickatus’s

-Develop large swings with Strongman + Nether

-Use Tome Of Origination to arrange big combos. Completing the quest should never be a high priority, but eventually when the quest completes, discounting high mana cards is powerful. Discounting Corrupt cards like Tickatus and Cthun pieces [or even Cthun himself] is awesome. 

-Cthun

Not a top deck at all but still a fun control deck with a lot of interesting combos.
