This is what you need:
step 3) play the DK: Uther of the Ebon Blade.
This is is perfectly playable without the OTK but since these last expansions Licensed Adventurer and Libram of Wisdom are such great additions for this combo. Cards like: Lady Liadrin and Lynessa Sunsorrow make sure you get the 0 cost librams.
- Eydis Darkbane and Libram of Wisdom can do a lot of damage
- Recurring Villain is a star when it comes to buffing it with your spells, but also with: Teron Gorefiend.
- Libram of Justice and Wild Pyromancer for a board clear.
Muligan for Licensed Adventurer and cheap cards.
