Themed White/Black Cleric

I'm a fan of mixed color decks; especially themed decks. After seeing some of the new sets and how there were many cards that aided multi-color decks, particularly certain theme decks (in this case clerics), I couldn't resist. The main attackers in this deck are the Doubtless One and the Vile Deacon, which become very large creatures, and in case of the Doubtless One, heals you when it deals damage. There's a lot of defense in this deck and ways to retrieve clerics from your graveyard should one or more of them die. Whipgrass Entangler, the ability to gain life, drain some life with Profane Prayers, and the ability to reduce damage should be enough to keep you ahead in the game. Suggestions and comments very much welcome (especially with the sideboard, which is filler).
