I opened a pack up this morning and low and behold it was a Desert Obelisk, instantly thinking, "Ah a Priest Deck filled with a couple of Spirit of the Dead, Seances, Unidentified Elixirs, Faceless Manipulator and of course the kicker the Desert Obelisk".  Faceless Manipulator has always been a favorite card because if needed you can copy an Opponent's minion, but when you add in cards like Northshire Cleric for drawing power, Modify your Spirit of the Dead to make it harder to kill until you can play them both, doubling all minions killed, then you add in Biosterous Bard boosting Health of all Minions. Then we have Fungal Enchanter healing your minions, Sandhoof Waterbearer to keep yourself and your minions healthy Stubborn Gastropod, Prince Valanar & Obsidian Statue for Defense, Drakkari Enchanter for doubling end of turn effects, Wretched Reclaimer (good way to double a minion while Spirit of the Dead is in play.  Bwonsamdi, the Dead to bring all those 1 cost minions to your hand, lastly Holy Nova as a Board Clearing & healing.

This deck can win without summoning the Desert Obelisk, but when you add in the small effect minions such as Boisterous Bard & Fungal Enchanter your minions are constantly being healed and their health increased slowly by 1 health per Bard.  You want to save your Divine Health for your Obsidian Statue making it harder to kill, if need be you can also use the Wretched Reclaimer to kill the Obsidian Statue after using it to attack and hopefully kill something before you kill the Statue which in turn kills a random enemy minion before coming back to full health and ready to buff.
