This is a super fun and easy deck to complete the rewards for Priest... and get some wins in the process. 

Basically, it's an aggro deck.  You just want to throw your Undead at your opponent and raise your deathrattle minions with the Amulet and then drop the bomb with the hero card. 

I've been able to run and gun with this up to 5 Diamond just having fun.  My deck tracker won't update so I am not able to get a tally for the win ratio.  Suffice it to say, it's effective.  The only downfall is that control can be difficult.  Other than that, have fun!
