How to Defeat Rafaam Using Kel'Thuzad in "An Evil Exchange" Tavern Brawl

Watch the video.

Kel'Thuzad's premade deck is more powerful than Rafaam during early to mid-game. Try to dominate the board faster using Gluth and Anub'Rekhans. Rafaam will be a big threat once he completed his staff / hero power. Kill your opponent as much as possible.
