Obsessive Herring Priest

E.T.C., Band Manager pool: 

Crazed Alchemist: usually first pick if u are going for Red Herring + Obsessive Fan combo

Lor'themar Theron: if its early enough in game and u havnt drawn card]Red Herring

Whirlpool: For matches such as Blood DK where combo is almost impossible to pull off or if u need an extra broad clear

Deck runs multiple ways to get additional copies of E.T.C. so in theory u should be able to grab more then one card most games :)
