I believe this baby is actually quite viable if the meta slows down. Self explanatory, just a control priest, play big boys and things from your deck, shuffle many reliquaries (with bloods and idols) and on slower match ups, kill your opponent with the shard.

I think the key cards for this archetype are Enthusiastic Banker and Cornelius Roame, since they'll thin your deck and give you that draw you need for playing the shard more consistently.
