In this video we take on The Lich King, the final boss of the Knights of the Frozen Throne expansion for Hearthstone, with a Priest deck that costs 200 dust to craft!
Code for deck: AAECAa0GAA8IhAGBAoUD8AOLBOAEgAbJBtAHywjXCvIMlg2hrAIA

Strat TL:DR: Build a board until the Frostmourne phase, use Shadow Word: Horror to transition, and continue through to finish him off while trading efficiently.
Mulligan: Northshire Cleric, and then anything low cost that you can use to defend it for card draw, such as Shadow Word: Pain or MINION.
Cards to Add: Lightwarden, Lightwell, and cards for the Divine Spirit/Inner Fire combo (however if you’re having bad luck with Obliterate, it can up the RNG requirement). Bonemare is also a good late game buffing card, giving you that 5/5 body and the +4/4 Taunt, but it does make a target susceptible to the Black Knight. Any high cost legendaries such as Dr. Boom would also be great.`
Cards to Remove: Elven Archer and Razorfen Hunter are both pretty average compared to other cards of similar value.
