Hearthpwn

This is a control paladin that survives until the late game and then finishes the opponent through attrition. Hakkar shuffles corrupted blood into both decks, putting a timer on the game that you can avoid by purifying your deck. Once you purify the Corrupted Bloods, they become random class cards for you to use (which extends your fatigue counter) and this enables your Lightforged Crusaders to generate a ton of resources for you to continue the game.

Also, Sathrovarr + Shirvallah, the Tiger lets you spike removal and healing in the late game, keeping your health above combo kill levels (effectively, this can be three 7/5 rush lifesteal minions that remove three threats and heal you for 21, for 9 mana and 2 cards, that also adds one of the combo pieces back to your deck)
