This control variant of the Warlock deck has had some success in the past. Now it's more refined with the inclusion of two new cards from Scholomance Academy.
Brittlebone Destroyer is perfect for Warlock, which can tap to activate this its minion destruction ability. The legendary Polekelt Keeper is a very unusual card that re-orders your deck to put the highest-cost cards on top.
All your best cards are just one tap away, increasing your chances of victory tremendously.
