This is really just another big priest isn't it

Big boys

All minions in this deck cost at least 5. This is because Y'Shaarj, Rage Unbound is much stronger when he recruits strong minions. It also means that Ressurect and Eternal Servitude will resummon strong minions. The fact half the deck has Deathrattle also means you benefit from both Shadow Essence and the ressurection spells. 

Tiny spells

Unless you're playing druid, you can't start the game with 5 mana. this means you're very vulnerable for 5 turns- unless you have strong, cheap spells. Priest lacks damaging spells tough, so you'll need an alternative. There's Mind Vision and Cloning Device to get minions from your opponent, and Psionic Probe for spells. For a more direct way of getting small minions from your opponent, look no further than Potion of Madness. Don't worry too much, you'll have 5 mana before you know it.

If you don't have Countess Ashmore, don't just replace it; also replace your Lifesteal minions with strong Deathrattle minions.
