How to use this deck (from what I assume we are getting with the new hero power meta)

This is all about late game. The point is to slam your opponent with your hero power at least 7-8 times a turn, for maybe up to a three damage fireblast.

Cards like Emperor Thaurissan are to "synergize" with Duplicate and Echo of Medivh. The point is to bring the combo cards such as Justicar Trueheart, Coldarra Drake, and Fallen Hero down to a low, reasonable mana price to where you can get value on the turn you drop those cards. These cards combined will do three damage for one mana, and you can use your hero power an unlimited amount of times per turn. This will allow synergy with the new giant, Frost Giant which can be dropped for a really low cost. 

This deck is also about staying alive to allow yourself to perform this combo. Cards like Sludge Belcher, Alexstrasza, Antique Healbot, Ice Barrier, and Ice Block are to keep you alive.

Other cards like Dr. Boom, Sylvanas Windrunner, Loatheb, and Flamestrike are to maintain a heavy board presence.

I do imagine this deck being somewhat weak against the aggro decks, but who knows. After all, this is just a theory. When the new expansion comes out, I will definitely try this deck to see if it works. Leave any comments as to how to make this deck better below. Thanks.
