This is based on my other control deck but I have tested and made some modifications.
The game finishers are Thogg or Cthun double battlecry.
The lighting bloom allows you to cast the card twice.
Lots of Card draw to get to your combo.
There is plenty of removal and heal and defense to last.
Double Thogg is fun.
This deck can add or alternate King Pharos and Naomi as extra finishers.
SO the main combo finisher is Cthun plus lighting bloom doubled by the hero power from the quest Corrupted Waters.
60 damage in one turn basically kills anything.
