Mulligans
General Mulligans
Quest: Logically you´ll play this turn 1 (Most of the time)
Cleric/Lightwarden Those are the best Minions to start with early as they aren´t threatened that much.
And you should also look out for Cheap heal Spells to Finish your Quest/Draw
Aggro Mulligans
Also, Against Aggo you should search for embrace the shadow with Flash Heal or circle of Healing for Removal
Some Shenaningans I´ve thought formed into yet another Deck.
Your Main Goal is to summon C´thuin with the Quest giving you some backup.
You mostly try to stay safe while drawing Cards with Northshire and killing Big Stuff/Threatening with Lightwarde.
This Deck currently Lacks Removal so you have to rely on your Minions for and Embrace the Shadow to keep you safe
If you manage to hit your Opponent hard enough early on you can use Embrace the Shadow to finish your opponent off.
