This deck involves around Curse of Agony and hitting face with both spells and the Questline.
Your #1 priority is using Tamsin Roame‘s effect to copy each Curse of Agony, preferably by turn 5. Total damage done from all Agonies will total 78, although against classes that don’t use much healing or armor one can suffice to copy just one of the Agonies if necessary as the total comes to just 48.
The rest is based around controlling board, healing, completing at least the first 2 parts of the questline (for the total 6 lifesteal damage to their face), and finding the opportunity to hit the opponents face with Soulfire or Demonic Assault.
