Rough Orzhov Deck in Preparation for Gatecrash

This deck is very unfinished. In casual play it is a bomb, but in tournament play it is a consistent loser. The deck is trying multiple strategies but does not have a finisher in any of them:

1. Play lots of enchantments leading to Sphere of Safety.
2. Cause lots of discard to play Shrieking Affliction.
3. Pack Rat (need I say more!!!).

Its a rough start all right. If I try to improve on any of these three strategies the other two become unworkable.
